do not approximate the aggregated test result.

AggregatedTestResultAction remembers the exact build # of the child build, so honor that number, and don't let MatrixBuild.getRunFor(Configuration) picks up some earlier run.

The problem was discovered in the following situation:

 - there's a matrix project M with single configuration X
 - M #868 run normally, with 69 failures.
 - M #869 run with 258 failures, and that was reported in MatrixTestResult.add(AbstractTestResultAction), updating  the total count.
 - but for whatever reason, X #869 is lost
 - now if you look at M #869 test report, you'll see 258 as the total count, but the detail drill down would show 69, from X #868.

(05:25:57 PM) veebers: Hi all, I  have an odd issue with the 'test results'
(05:26:12 PM) veebers: In this result: Test Result (258 failures / +189) where could the +189 come from?
(05:26:20 PM) veebers: I can only actually see 69 failed tests :P
(05:26:48 PM) kohsuke: it means comparing to the last test result, you got 189 more failure
(05:27:37 PM) veebers: ah ok, but how can I have +189 failing tests when there are only 69 failed this time around?
(05:28:21 PM) kohsuke: I wonder if it cuts off the summary display at 70 (out of your 258 failures)?
(05:29:48 PM) veebers: Hmmm, kohsuke I don't know about that. Clicking the 'show all failed tests'  only shows 69 tests :P
(05:30:22 PM) veebers: and when I look at a prev. failing test, one that has ~200 fails
(05:30:24 PM) veebers: it shows the lot
(05:31:07 PM) kohsuke: veebers: want to do the screenshot?
(05:34:59 PM) veebers: kohsuke: sure: http://static.inky.ws/image/2143/image.jpg
(05:35:40 PM) kohsuke: this is a matrix project that just has one configuration?
(05:35:49 PM) kohsuke: Or is it a partial re-run?
(05:35:53 PM) mode (+o abayer) by ChanServ
(05:36:46 PM) veebers: first option. Only one config
(05:37:56 PM) kohsuke: I wonder if this is some kind of rendering gritch
(05:38:06 PM) kohsuke: perhaps if somehow it's showing the data of the previous run?
(05:38:24 PM) kohsuke: 69+189=258 can't be a coincidence
(05:38:53 PM) kohsuke: is this instance publicly visible?
(05:39:25 PM) veebers: err not that one, just checking if the results are published to the public one
(05:41:16 PM) veebers: hmm, that's odd. The publicly avail. one isn't showing the right details :P
(05:41:24 PM) kohsuke: URL?
(05:41:26 PM) veebers: well, perhaps there is something screwy with that setup
(05:42:14 PM) veebers: kohsuke: https://jenkins.qa.ubuntu.com/job/dx-autopilot-run/869/
(05:43:33 PM) veebers: kohsuke: although I don't think that's going to be much help as that gives me a 500 error :P
(05:43:45 PM) kohsuke: that's a bug of its own
(05:43:51 PM) kohsuke: I think I can fix that one
(05:50:29 PM) kohsuke: veebers: I think I have a hypothesis
(05:51:00 PM) kohsuke: when you do click that 69 failed tests reported under a configuration, I suspect you'll be actually taken to the different build number
(05:51:23 PM) kohsuke: likely the same configuration build of the previous one
(05:53:02 PM) veebers: kohsuke: hmm, not sure that's it.
(05:53:10 PM) veebers: it's the same build number all over
(05:53:53 PM) kohsuke: I'm pretty sure that's it
(05:54:01 PM) kohsuke: let me think of other ways to prove this
(05:54:27 PM) veebers: sure
(05:54:36 PM) kohsuke: try /job/dx-autopilot-run/869/label=1EBEE0FF-DAC9-11DF-BBDA-64A98C34D485/parentBuild/
(05:54:43 PM) kohsuke: and I predict you'll see #868 in the UI
(05:54:45 PM) veebers: so, the public page there says: Test Result (258 failures / +189)
(05:55:16 PM) veebers: When I click that link in the private server it takes me to that report you saw in the screenshot
(05:55:43 PM) veebers: which says: .../869/testReport/
(05:55:52 PM) veebers: and any other link on that page references 869
(05:56:04 PM) veebers: so perhaps it's somewhere in the background that might be accessing a prev build?
(05:56:36 PM) veebers: i.e. whatever builds up the top graph bar (at the top of the page) in server end rendering?
(05:56:50 PM) kohsuke: does /job/dx-autopilot-run/869/ show gray ball?
(05:57:27 PM) veebers: no, it shows the default config
(05:57:37 PM) veebers: (yeah, something is wrong with the public facing one :P)
(05:59:29 PM) veebers: not sure why you can't click through
(06:00:40 PM) veebers: kohsuke: ah, looks like you are correct
(06:00:50 PM) veebers: I was looking in the wrong place
(06:01:01 PM) veebers: kohsuke: d'oh, thanks for pointing that out :)
(06:01:41 PM) kohsuke: OK, I understand what happened
(06:02:38 PM) veebers: so yeah, clicking on that config, I can see the line: Started by upstream project dx-autopilot-run build number 868
(06:04:37 PM) kohsuke: #869 really did have 258 failures, but for some reason Jenkins lost the record of it
(06:05:02 PM) kohsuke: and when it's displaying this to you, it's approximating the lost record by using the nearest build, that was #868
(06:05:20 PM) kohsuke: and that's why the public instance, which runs ancient version of Jenkins, reports NPE
(06:05:30 PM) kohsuke: this version doesn't have that approximation feature
(06:05:42 PM) kohsuke: veebers: BTW you really should upgrade that publicly facing instance
(06:06:00 PM) kohsuke: there have been some security advisories issued since then
(06:06:11 PM) veebers: kohsuke: Makes sense, will get onto that
(06:06:30 PM) kohsuke: I'm fixing this in the trunk so that it doesn't incorrectly approximate here
(06:06:36 PM) veebers: nice
