evolve: add test to demonstrate issue6203

Current logic of content-divergence resolution contains a bug that
if resolution parent is not the parent of any of the two divergent
changesets, it could undo some changes.

I think a good solution for this is to first relocate the divergent cset
to it's obsolete parent's successor if applicable and then perform
the content-divergence resolution.

Next patch will fix the issue.

and the not file mod thing at the top, it will show the same "nothing unselected
