evolve: add test for the case where public divergence on difference parents

This test make sure that public divergence resolution also handle the case when
divergentes changeset does not share the same parent at one end because one end
simply rebase. The other side has actual an actual diff change.

For now this would work only for the case when we need to relocate
the mutable one. Other case is still left to work on.

** Testing resolution of orphans by `hg evolve` where an obsolete changeset has
multiple successors **
