tests: add test showing that rebase of extinct commit with successor fails

As the test case shows, attempting to rebase a commit that has a
successor that is not in the rebase set and not in the destination
currently fails because it "will cause divergences". However, it
doesn't seem like there's any harm in skipping the extinct commit. I
suspect this case missed simply because extinct revisions are usually
hidden.

 Start rebase from a commit that is obsolete but not hidden only because it's
 a working copy parent. We should be moved back to the starting commit as usual
 even though it is hidden (until we're moved there).

 Divergence cases due to obsolete changesets
 -------------------------------------------
 
 We should ignore branches with unstable changesets when they are based on an
 obsolete changeset which successor is in rebase set.

 Changeset d and its descendants are excluded to avoid divergence of d, which
 would occur because the successor of d (d') is also in rebaseset. As a
 consequence f (descendant of d) is left behind.

 If the rebase set has an obsolete (d) with a successor (d') outside the rebase
 set and none in destination, we still get the divergence warning.
 By allowing divergence, we can perform the rebase.
