Clean up some more carnage from D6416

Summary: rPad17c99c1b0222292a47ca79561a356cb8b5a5d5 stopped the fatal and this provides the forward fix. I think this is what a forward fix is anyway.

Test Plan: viewed a revision (D63 is my boy) and no fatals

Fix fatal when deleted user is subscribed to a task and we generate an email to them

Summary: Fixes T3528. We won't be able to load the user if they've been deleted, and will fatal a few lines later on `$user->getID()`.

Test Plan: I'm going with my gut on this one.

Fix two problems with actor order in Asana bridge

Summary: We attempt to choose the most reasonable actor when synchronizing to Asana, but Asana is seeing the sync choose a less-reasonable actor. I spotted two places where the order may get disrupted; make sure we retain order. This is somewhat tricky to repro locally (it depends on things like native account order) but I think this is the right fix. If not, I'll add more logging. Ref T2852.

Test Plan: Used `bin/feed republish` to sync Asana events.

A pull from GitHub recently added `mysql.port`, for explicitly configuring the MySQL port. See:

Methods for reading reviewers from edges in differential

Summary: Add `getReviewerStatus` to get an array of `DifferentialReviewer` objects. The method `needReviewerStatus` in `DifferentialRevisionQuery` loads the edges into the revisions loaded.

Test Plan: Added `->needReviewerStatus(true)` to `DifferentialRevisionSearchEngine` and checked through logging that the data was being loaded correctly.

Remove calls to DifferentialRevision::loadRelations from commit workers

Summary:
Remove ocurrences of `loadRelations` in workers.

One was simply unnecesary, no subsequent call to `getReviewers` or `getCCPHIDs` was made.
The other was replaced with the nicer `DifferentialRevisionQuery` using `needRelations` and `needReviewerStatus` (for future upgrade).

Test Plan:
Land a revision into a tracked repository and check the parser worker attached the commit correctly.
For the owners worker I just checked it didn't crash into a hundred tiny pieces.

Improve Asana API error handling in Doorkeeper

Summary:
Ref T2852. We need to distinguish between an API call which worked but got back nothing (404) and an API call which failed.

In particular, Asana hit a sync issue which was likely the result of treating a 500 (or some other error) as a 404.

Also clean up a couple small things.

Test Plan: Ran syncs against deleted tasks and saw successful syncs of non-tasks, and simulated random failures and saw them get handled correctly.
