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().

KeyError: b'topic' on history-rewriting commands (issue6500)

  $ . $TESTDIR/testlib/common.sh

Making sure we're not caching .topic() results for memctx or anything else that's not stored on-disk

  $ hg init issue6500-caching-memctx
  $ cd issue6500-caching-memctx

  $ cat >> $HGRCPATH << EOF
  > [extensions]
  > evolve =
  > topic =
  > EOF

for this test we need 2 changesets with amend_source, one with topic and one without

  $ hg topics foo
  marked working directory as topic: foo
  $ echo apple > a
  $ hg ci -qAm 'apple'
  $ echo apricot > a
  $ hg ci --amend -m 'apricot'

not using `hg topics --clear -r .` here because that would remove amend_source, see _changetopics()

  $ hg topics --clear
  $ hg ci --amend -m 'no foo apricot'

  $ hg log --hidden -r 1+2 -T '{rev}: {join(extras, " ")}\n'
  1: amend_source=* branch=default topic=foo (glob)
  2: amend_source=* branch=default (glob)

creating and handling 2 memctx instances (based on 1 and then 2) should work

  $ hg touch --hidden -r 1+2 --duplicate
  switching to topic foo

make sure extras stay the same

  $ hg log --hidden -r 3+4 -T '{rev}: {join(extras, " ")}\n'
  3: __touch-noise__=* amend_source=* branch=default topic=foo (glob)
  4: __touch-noise__=* amend_source=* branch=default (glob)
