[issue34621] uuid.UUID objects can't be unpickled in older Python versions (<3.7)

Tal Einat added the comment: Note that the original fix, in PR GH-9133, contained a bug: UUID objects with `is_safe` set to `SafeUUID.unknown` would cause an exception if unpickled with Python <3.7. This was reported by Thomas Wiebe in a comment to a commit in that PR:
