evolve: rely on resolutionparent when relocating divergent csets

As discussed with Pierre-Yves the current behavior of resolving
content-divergence when parent changes:

1) First we decide the resolution parent (the parent where resolution
   cset will be based on)
2) Relocate both the divergent csets to the resolution parent (if a
   cset is already on resolution parent, nothing to do for it)
3) Perform 3-way merge to create the resolution cset of content-div

This patch makes sure that we rely on that decided resolution parent,
when relocating divergent csets to the parent where the resolution cset
will be based on.

====================================
Testing head checking code: Case D-3
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 3: multi-changeset branch, split on multiple new others, only one of them is pushed

.. old-state:
..
.. * 2 changesets branch
..
.. new-state:
..
.. * 2 new branches, each superseding one changeset in the old one.
..
.. expected-result:
..
.. * pushing only one of the resulting branch (either of them)
.. * push denied

Actual testing
--------------

  $ hg push --rev 'desc(A1)'
  pushing to $TESTTMP/D3/server (glob)
  searching for changes
  abort: push creates new remote head f6082bc4ffef!
  (merge or see 'hg help push' for details about pushing new heads)
  [255]
  $ hg push --rev 'desc(B1)'
  pushing to $TESTTMP/D3/server (glob)
  searching for changes
  abort: push creates new remote head 25c56d33e4c4!
  (merge or see 'hg help push' for details about pushing new heads)
  [255]

Extra testing
-------------

In this case, even a bare push is creating more heads

  $ hg push
  pushing to $TESTTMP/D3/server (glob)
  searching for changes
  abort: push creates new remote head 25c56d33e4c4!
  (merge or see 'hg help push' for details about pushing new heads)

  $ cd ../..
