topic: check that repo.currenttopic is set before using it as an argument

repo.currenttopic can be an empty string, which means there's no current topic
set. This fact can be used to short-circuit some checks.

Also, this avoids passing an empty string as an argument to topic() revset.

Testing `hg stack` on complex cases when we have multiple successors because of
divergence, split etc.
