next: filter unstable targets by topic only when there's no --no-topic

Otherwise --no-topic makes no difference in how hg next works with unstable
targets.

Now that aspchildren filtering code actually works, this patch makes hg next
behave correctly when dealing with unstable changesets with a different topic.
