Also refactoring existing checks somewhat to check when tree is finished rather than on individual nodes.
That relaxes requirements on individual overlays, I think we say in documentation today that an overlay shall be a valid tree in itself. That is however not strictly needed as it is not intended to be usable by itself.
With this change the "defect" in VSS 3.1 with a branch without description would had been detected
