Fix T49856: Blender 2.78 crashes after loading data from a blendfile

Issue here was that py API code was keeping references (pointers) to the
liniked data-blocks, which can actually be duplicated and then deleted
during the 'make local' process...

Would have like to find a better way than passing optional GHash to get
the oldid->newid mapping, but could not think of a better idea.
