Fix reparenting errors in serializer ...
Fix cases where AnyDescendantWasReparented() fails to notice a
reparenting occurrence, because it stops recursing when there is an
unignored node. This is correct; however, sometimes it thinks
something is unignored when it's really ignored, because there are two
places to look for this info -- currently it only looks to see if
the node was ignored at the end of the previous serialization, but it
also needs to check if the node has recently become ignored.
In release builds, these illegal reparenting crashes cause a Reset(),
which is a fail safe, but also indicates there's an inconsistency,
leads to performance problems and causes virtual buffer resets.
Cleaning up these types of issues over time will improve stability,
performance and predictability.
