evolve: move logic to resolve phase-divergence in a new function

This patch moves logic which does the revert and create a commit on top of
public changeset because we need to repeat that logic while handling
continuation of `hg evolve` when there are conflicts while rebasing the
phase-divergent changeset.

Test for stable ordering capabilities
