story #7599 have a dedicate queue for git events

2 legacy events where not moved to the dedicated queue:
- change of access on gitshell repo
- deletion of gitshell repo

Those two only represent a tiny fraction of the git repo and are meant to be
disapear at sometime. It's not worth the effort to create a new dedicate queue
(git/root) for this.
