LibOverride: Make process checking validity of hierarchy roots more robust.
Code was not really designed to hanlde corrupted (e.g. local ID) root
hierarchies, now it should handle better those invalid cases and restore
proper sane situation as best as possible.
Fixes crashes with some corrupted files from Blender studio.
