uncommit: simplify condition for keeping commit...

uncommit: simplify condition for keeping commit We used to keep the commit if it would have become empty and --keep was not passed. Since we just changed it so we also keep it if any patterns were passed on the command line, the only remaining case where we prune the commit is when no arguments were passed and --keep was not passed either, we can simplify the "not files and not allowempty" to just "not allowempty". Let's also rename "allowempty" to "keepcommit" since it's no longer about allowing an empty commit. Differential Revision: https://phab.mercurial-scm.org/D2891
