build.webkit.org/dashboard incorrectly shows interrupted builds as green
https://bugs.webkit.org/show_bug.cgi?id=122732

Reviewed by Tim Hatcher.

* BuildSlaveSupport/build.webkit.org-config/public_html/dashboard/Scripts/BuildbotIteration.js:
(BuildbotIteration.prototype.update): Removed a special case for status 4 (EXCEPTION).
I don't see it occur any time in recent history, but judging from what happens for
status 5 (RETRY), we can just finish this function normally.
Record overall text description for iteration as BuildbotIteration.text.

* BuildSlaveSupport/build.webkit.org-config/public_html/dashboard/Scripts/BuildbotTesterQueueView.js:
(BuildbotTesterQueueView.prototype.update.appendBuilderQueueStatus): If an iteration is a failure,
but no tests failed, make it yellow, and use buildbot-provided description for it.
