Fix (studio reported) missing object's parent handling in readfile expand code.

This would prevent loading a parent that would only be referenced by
children during a linking operation.

Looks like this missing bit of code has been there since the stone ages,
it is fairly baffling to find that such critical low-levels mistakes can
survive decades in a codebase...

Note that such fully-indirectly linked parent object is not instantiated
in scene currently, this is fairly bad I think, but kind of a different
issue.
