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.

=========================================================
Test the proper behavior of evolve during merge conflict.

Initial setup

  $ safesed() {

create a simple repo

  $ hg init repo
  $ cd repo

  $ hg add babar
