evolve: clean merge state when content divergence resolution has no changes

This patch backs out b723805d7fe1, which only hid the problem.

Usually mergestate is cleared (or should be cleared) when creating a new
changeset, but sometimes there are situations when there's nothing to commit.

When solving content divergence resulted in no changes and no new changesets
were created, mergestate was left untouched. That's a problem because sometimes
mergestate contains files with conflicts that were already resolved by user,
and such mergestate only applies to the current wdir parent. Since evolve has
already dealt with the current wdir parent successfully when it reached this
code, this is a good place to clean the mergestate.

Testing core behavior to make sure we did not break anything
============================================================

Pushing a first changeset

  $ cd client
  $ echo aaa > aaa
  $ hg add aaa
  $ hg commit -m 'CA'
  $ hg outgoing -G
  comparing with $TESTTMP/main (glob)
  searching for changes
  @  0 default  draft CA
  
  $ hg push
  pushing to $TESTTMP/main (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

Pushing two heads

  $ echo aaa > bbb
  $ hg add bbb
  $ hg commit -m 'CB'
  $ echo aaa > ccc
  $ hg up 'desc(CA)'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg add ccc
  $ hg commit -m 'CC'
  created new head
  (consider using topic for lightweight branches. See 'hg help topic')
  $ hg outgoing -G
  comparing with $TESTTMP/main (glob)
  searching for changes
  @  2 default  draft CC
  
  o  1 default  draft CB
  
  $ hg push
  pushing to $TESTTMP/main (glob)
  searching for changes
  abort: push creates new remote head 9fe81b7f425d!

  $ hg push -r 'desc(CB)'
  pushing to $TESTTMP/main (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files

Pushing a new branch

  $ hg branch mountain
  marked working directory as branch mountain
  (branches are permanent and global, did you want a bookmark?)
  $ hg commit --amend
  $ hg outgoing -G
  comparing with $TESTTMP/main (glob)
  searching for changes
  @  3 mountain  draft CC
  
  $ hg push 
  pushing to $TESTTMP/main (glob)
  searching for changes
  abort: push creates new remote branches: mountain!
  (use 'hg push --new-branch' to create new remote branches)
  [255]
  $ hg push --new-branch
  pushing to $TESTTMP/main (glob)
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 1 changesets with 1 changes to 1 files (+1 heads)
  1 new obsolescence markers

Including on non-publishing

  $ hg push --new-branch draft

  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 3 changes to 3 files (+1 heads)

setup, two repo knowns about two small topic branch

We turn different topic to public on each side,

  $ hg -R repoA phase --public topicA

Pushing should complain because it create to heads on default
