Fix unit tests and save problems

(note; contrary to previous commits, saving 0.4 OARs is actually broken since serialized objects in inventories are not yet converted properly).
Firstly, if you can save a version 1.0 OAR then you can load it too.
Secondly, closing the save stream even on success before assets/objects are saved is a bad idea
