evolve: make sure we don't stop after evolution of obsparent (issue5881)
Before this patch, we were not handling the case when revset
given by user also contain wdir parent which is obsolete.
We were explicitly checking if wdir parent is obsolete, then update
to its successor and return; without checking if we still have
some revisions to be evolved.
This patch make sure that after it update to the successor of
obsolete parent it doesn't stop and continue to evolve other remaining
revisions.
Changes in tests/test-evolve-issue5881.t reflect the fixed behaviour.
