Raise the error when repository storage move fails

What does this MR do?

This is a partial solution to #333277 (closed)

Right now when repository storage moves fail, the only way to tell is to check the state column in the database, then try and correlate that to logs for the specific repository to see what failed. This makes it very difficult to debug especially since the sidekiq job is considered successful. Instead we should explode and let sidekiq error reporting tell the user that the move failed.
