[IMP] osv: added test for parent_store computations + fix for another edge case

The yaml test create a tree structure and modifies it by copying nodes
around and then moving them, checking that the child_of operator keeps
working afterwards. This test caught another edge case, as a follow-up
to the case of bug 708603
