remote: don't try to update FETCH_HEAD if no extra heads exist
Don't try to update anything if there are no heads to update. This
saves us from trying to look into a fetch refspec when there is none.
A better fix for compatibility with git when using remotes without
refspecs is still needed, but this stops us from segfaulting.
