topic: display a hint pointing at help when a topic becomes non-empty

This is an attempt at avoiding "mistakes" by new users of topics when
they pull a topic and publish its changesets while being checked out. In
this case, the topic will become empty but still be active; however, if
this is a "foreign" topic, the user will not likely want to keep it
active for the next commit operation. So we add a hint message pointing
at general help of "topics" command so that they can eventually do
something and learn about "hg topics --clear".
