tests: add tests of jj move to ancestor, showing lost branch

Browse Source 
I noticed earlier today that branches get lost (stuck on a hidden
commit) when you move part of a change to an ancestor. This patch adds
tests for both of those cases, showing the bug. There's no special
logic for this case in the CLI crate, so we should be able to test it
in the library crate instead, but since I have already written the
tests, maybe we can keep them.
