Always return the output from ref-update hook

Change I5905c44c7 moved the invocation of the ref-update hook out of
the ReceiveCommits implementation and into CommitValidators. Since
then, the output of the ref-update hook is not sent back to the git
client except in the case of an error or rejection.

Update the handling of the ref-update hook in the plugin so that its
output is returned back to the caller as a commit validation message
which is then sent to the client.
