phabricator: post revisions in ascending topological order (issue6241)

The parent in phabricator ends up being the last revision posted, so sorting the
user input into ascending order should be enough to preserve the proper
relationships.

  $ python $TESTTMP/timeout.py -s INT 1 hg sleep 2
  shutting down cleanly
  press ^C again to terminate immediately (dangerous)
  end of unsafe operation
