Update remote happens through Gitaly only
This change makes closes another migration! And remotes tests around it,
mostly due to stubbing this was needed. Also, these are tested on the
Gitaly side too:
- https://gitlab.com/gitlab-org/gitaly/issues/791

https://gitlab.com/gitlab-org/gitaly/blob/6dd74543f6af8ebcf22aa10e39da004f388fdda5/internal/service/repository/fetch_remote_test.go
Closes https://gitlab.com/gitlab-org/gitaly/issues/789
