git fetch-pack: do not complain about "no common commits" in an empty repo

If the repo is empty, it is obvious that there are no common commits
when fetching from _anywhere_.

So there is no use in saying it in that case, and it can even be
annoying.  Therefore suppress the message unilaterally if the repository
is empty prior to the fetch.
