Remove rescue of Gitlab::Git::CommitError at UserMergeToRef RPC
We've been experiencing transient Gitlab::Git::CommitError
that were being rescued at gitaly-ruby
. They might be related to
conflicts or errors during git update-ref
.
This MR removes the rescue and also make the error messages more detailed for further investigation at Sentry.
Ideally we should move the rescuing to the client instead.
Edit: We've noticed it's due to concurrent calls to this RPC.
Further details at #1782 (closed).
