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.
