tests: demonstrate broken rebase of merge with p1's successor in dest
The fix in 8ede973597fd (rebase: handle successor targets (issue5198),
2016-04-11) only fixed the case where p2's successor was in the
destination, and only when the successor was exactly the destination
(i.e. not when the successor was an ancestor of it). This patch adds a
test case for when p1's successor is in the destination. It adds
another one for when the successor is an ancestor of the
destination. To do that simply, it also rewrites the test case using
drawdag.
