suppress "(Recording state in git)" message when committing change to remote state

This was shown redundantly for a tricky reason -- while it runs
inside a doSideAction block that would appear to supress it,
the action being run is in a different state monad; for the remote,
and so the suppression doesn't work.

Always suppressing the message when committing to a local remote is
ok do to though -- it mirrors the /dev/nulling of the git annex shell commit
output. And it turns out that any time there is a git-annex branch state
change to commit on the remote, the local repo has also had a similar
change made, and so the message has been shown already.
