Fix bug where setting phantom on a prim would result in a server log message rather than setting phantom.

This was an oversight when removing some race conditions from PhysicsActor setting recently.
Regression tests extended to probe this code path.
Extending regression tests required implementation of a BasicPhysicsPrim (there was none before).  However, BasicPhysics plugin is still of no current practical use other than to fill in as a component for other parts of regression testing.
