Fix a bug where linking a non-physical prim with a physical prim as root would make the non-physical prim phantom rather than part of the physics object.

On region restart, the whole object would become physical as expected.
Observed behaviour from elsewhere is that all prims in a new linkset should take on the status of the root prim.
Add regression test for this behaviour.
