The status of a A/B testing request always eventually becomes "Failed"
https://bugs.webkit.org/show_bug.cgi?id=141523
Reviewed by Andreas Kling.
The bug was caused by /api/build-requests always setting the status of a build request to 'failed' when
'failedIfNotCompleted' was sent by the buildbot sync'er.
Fixed the bug by only setting the status to 'failed' if it wasn't set to 'completed'.
