subrepo: don't pass the outer repo's --rev or --branch to subrepo outgoing()
The previous behavior didn't reflect what would actually be pushed- push will
ignore --rev and --branch in the subrepo and push everything. Therefore,
'push -r {rev}' would not list everything, unless {rev} was also the revision of
the subrepo's tip. Worse, if a hash was passed in, the command would abort
because that hash would either not be in the outer repo or not in the subrepo.
