tests: add tests for resolving content-divergence when different parents
This patch adds more tests for cases when we try to resolve content-divergence
when they are on different parents.
The last test shows the we are somehow missing the relocated commit in
interrupted transaction. This will be fixed in next patch.
** Test for handling of content divergent changesets by `hg evolve` **
