Improve check for overlapping FK targets on sibling classes

Fixed bug where ORM relationship would warn against conflicting sync
targets (e.g. two relationships would both write to the same column) for
sibling classes in an inheritance hierarchy, where the two relationships
would never actually conflict during writes.
