Issues like https://gitlab.com/gitlab-org/gitlab/issues/34749 show, that
the worker is vulnerable for exceptions happening during model update in
DB. What's worse is that exceptios happening on this level, are failing
the whole execution of StuckCiJobsWorker, which unnoticed ends with
thousands of stale pending/running/scheduled jobs waiting in the queue.

This commit re-uses the fix added with
https://gitlab.com/gitlab-org/gitlab/merge_requests/19150 to properly
handle and log such exceptions and drop the jobs regardless of them.
