Remove needs_own_queue tag from HashedStorage workers

After this change, jobs from these workers don't need their own queue
anymore. This won't be a problem for both GitLab.com or self-managed
instance because those workers were a part of the migration from legacy
git storage to hased storage. At this point, the migration is done.
There shouldn't be any migration job in the future.
