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().

=============================================================
Tests the resolution of public content divergence: main cases
=============================================================

This file intend to cover all the common cases of public content divergence.
That is all the variant of:
parent: same/different
relocation: [no-]conflict
merging: [no-]conflict

Setup

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

Testing when same parent, no conflict:
--------------------------------------

Prepare the repository:

  $ hg init pubdiv1
  $ cd pubdiv1
  $ for ch in a b; do
  >   echo $ch > $ch;
  >   hg ci -Aqm "added "$ch;
  > done;
  $ hg glog
  @  1:5f6d8a4bf34a added b
  |   draft
  |
  o  0:9092f1db7931 added a
      draft
  

Make an amend and change phase to public:

  $ printf "I am first\nb\n" > b
  $ hg amend
  $ hg phase --public

Amend again to create a cset divergent to public one:

  $ hg up 1 --hidden -q
  updated to hidden changeset 5f6d8a4bf34a
  (hidden revision '5f6d8a4bf34a' was rewritten as: 44f360db368f)
  working directory parent is obsolete! (5f6d8a4bf34a)

  $ echo "I am second" >> b
  $ hg ci --amend -m "updated b"
  1 new content-divergent changesets

  $ hg glog
  @  3:dcdaf152280a updated b
  |   draft content-divergent
  |
  | o  2:44f360db368f added b
  |/    public
  |
  o  0:9092f1db7931 added a
      public
  

Lets resolve the public content-divergence:

  $ hg evolve --content-divergent
  merge:[2] added b
  with: [3] updated b
  base: [1] added b
  merging b
  0 files updated, 1 files merged, 0 files removed, 0 files unresolved
  committed as b11d193ede1d
  working directory is now at b11d193ede1d

Following graph log shows that it correctly merged the two divergent csets:
