Clear context when scheduling mirroring jobs
requested to merge reprazent/gitlab-ee:bvl-clear-context-metadata-when-scheduling-mirrors into master
What does this MR do?
The UpdateAllMirrorsWorker could get scheduled from a request (from
a webhook) for a certain project.
This means that it would get the pointing to the project the request
was performed for. But since the UpdateAllMirrorsWorker could
schedule updates for other projects, we need to clear that metadata so
it doesn't propagate to those jobs that are being scheduled.
