changegroup: properly compute common base in changeggroupsubset (issue4736)

The computation of roots was buggy, any ancestor of a bundled merge which was
also a descendant of the parents of a bundled revision were included as part of
the bundle. We fix it and add a test for strip (which revealed the problem).

Check the test for a practical usecase.
