Geo - Schedule the repositories deletion after project removal

What does this MR do?

While removing a project, Geo leaves +deleted folder behind on secondaries. This happens because GitlabShellWorker that is responsible for deleting this folder is inside a run_after_commit callback since we don't perform any database operation this callback will never be triggered.

The changes in this MR is to schedule the repository deletion to remove the +deleted folder after we trash the repositories in EE::Projects::DestroyService#geo_replicate method.
