tests: add more tests related to stabilization of orphaned merge commit
This patch more tests related to stabilization of orphaned merge commit.
Stabilization of a merge changeset with both the parents is not supported right
now and prints a message on how to do that. Maybe we should do that internally
as a part of `hg evolve` but I need to think about this.
** Testing resolution of orphans by `hg evolve` when merges are involved **
