evolve: fix confusion in branch heads checking logic when topic in play

To provide some context, when topics are in play the branchmap cache
we store contains the branch info of a rev as "branch:topic" format IIUC.

Assuming that is right, now in present code we don't actually cover
this part that "when looking for branch heads where we also have active
topic we should look for branch='branch_name:topic' instead".
And we get wrong branch heads as a result.

This patch make sure that we pass right candidate to find branch heads
using branchmap.branchheads() by overriding the localrepo.branchheads()

Changes in test file reflect the fixed behavior.

+====================================================
+Tests the resolution of content divergence: metadata
+====================================================

This file intend to cover cases focused around meta data merging.

Setup
-----

  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc|firstline}\n {phase} {instabilities}\n\n"
  > [phases]
  > publish = False
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Check we preserve the author properly
-------------------------------------

Testing issue6113 to make sure that content-divergence resolution don't
replace initial author with the user running the resolution command:

  $ hg init userfoo
  $ cd userfoo
  $ unset HGUSER
  $ echo "[ui]" >> ./.hg/hgrc
  $ echo "username = foo <[e-mail]>" >> ./.hg/hgrc
  $ for ch in a b c; do
  > echo $ch > $ch;
  > hg add $ch;
  > hg ci -m "added "$ch;
  > done;

  $ cd ..
  $ hg init userbar
  $ cd userbar
  $ unset HGUSER
  $ echo "[ui]" >> ./.hg/hgrc
  $ echo "username = bar <[e-mail]>" >> ./.hg/hgrc
  $ hg pull ./../userfoo -q

  $ cd ../userfoo
  $ hg up -r "desc('added b')"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo c > c
  $ echo e > e
  $ hg add c e
  $ hg ci -m "added c e"
  created new head

  $ hg up -r "desc('added b')"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo cc > c
  $ hg add c
  $ hg ci -m "added c"
  created new head

  $ hg prune -r "min(desc('added c'))" -s "desc('added c e')"
  1 changesets pruned
  $ hg prune -r "min(desc('added c'))" -s "max(desc('added c'))" --hidden
  1 changesets pruned
  2 new content-divergent changesets

  $ hg glog
  @  4:6c06cda6dc99 added c
  |   draft content-divergent
  |
  | *  3:0c9267e23c9d added c e
  |/    draft content-divergent
  |
  o  1:1740ad2a1eda added b
  |   draft
  |
  o  0:f863f39764c4 added a
      draft
  

  $ cd ../userbar
  $ hg pull ./../userfoo -q
  2 new content-divergent changesets

  $ hg evolve --content-divergent --any
  merge:[3] added c e
  with: [4] added c
  base: [2] added c
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Make sure resultant cset don't replace the initial user with user running the command:
  $ hg log -r tip
  changeset:   5:443bd2972210
  tag:         tip
  parent:      1:1740ad2a1eda
  user:        foo <[e-mail]>
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     added c e
  
  $ cd ..

Testing the three way merge logic for user of content divergent changesets
--------------------------------------------------------------------------

  $ hg init mergeusers
  $ cd mergeusers
  $ for ch in a b c; do
  > touch $ch
  > hg add $ch
  > hg ci -m "added "$ch
  > done;

  $ hg amend -m "updated c"
  $ hg up -r 'desc("added c")' --hidden -q
  updated to hidden changeset 2b3c31fe982d
  (hidden revision '2b3c31fe982d' was rewritten as: 464e35020fd0)
  working directory parent is obsolete! (2b3c31fe982d)
  $ echo coco > c

1) when one user is different wrt base
--------------------------------------

Insert a diverging author name:
  $ hg amend -u 'foouser'
  2 new content-divergent changesets

Run automatic evolution:
  $ hg evolve --content-divergent
  merge:[3] updated c
  with: [4] added c
  base: [2] added c
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 932d6ceb7672

  $ hg log -r tip | grep "^user"
  user:        foouser

  $ hg strip . -q --config extensions.strip=
  2 new content-divergent changesets

2) when both the user are different wrt base
--------------------------------------------

  $ hg up -r 'max(desc("updated c"))'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -u 'baruser'

Run automatic evolution:
  $ hg evolve --content-divergent
  merge:[4] added c
  with: [5] updated c
  base: [2] added c
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 202a770d8c1f

  $ hg log -r tip | grep "^user"
  user:        baruser, foouser

  $ cd ..
