tests: add an explicit destination in some rebase tests

As we will make 'rebase' behave more like 'merge', it will no longer pick
'max(branch(.))' as the default destination. We have to hard code the expected
destination is multiple tests where it matters. After a careful inspection none
of theses tests really cares about the default destination behavior and just
omitted one out of laziness.
