topic: use dirstate.branch() instead of wdir.branch()

Since we wrap context.branch method to return branch in FQBN format already, we
cannot simply use its result with formatfqbn() again. Let's use something that
we don't wrap in topic extension, such as dirstate.branch().

  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
