topic: suggest to clear a topic that becomes empty

We add a hint suggesting "hg topic --clear" when a topic becomes empty.
This usually happens when all its changesets get public, that is when
the user does a 'phase -p' or when they pull from a server. To
discriminate relevant cases for which we should display the hint (and
typically exclude explicit 'hg topic --clear' operation), we look for
the transaction "type" to only consider 'phase' or 'push' transaction.
In the latter case, the transaction name is not simply 'push-response'
but it also included the remote URL so we need to match on string
content.

   active topic 'other' is now empty

 After changing the phase of all the changesets in "other" to public, the topic should still be active, but is empty. We should be better at informating the user about it and displaying good data in this case.
