Fix issue where loading OARs could sometimes result in link numbers being reordered.

Browse Source 
This was because the parts in scene objects were sometimes not serialized in link order.
This is perfectly fine since the parts still have the right link numbers, but an extra fix to adjust for this
had not been done in the SerialiserModule methods that OAR loading used.
Add regression test for same.
