Comment out attachments code in Scene.IncomingCreateObject(UUID userID, UUID itemID) for now

As far as I can see, this is only invoked by a PUT request to ObjectHandlers, which is not being used anyway.
Invoking attachments code at this point is probably inappropriate since it would still be invoked when the client entered the scene.
Being commented to simplify analysis of attachments issues.  Can be uncommented when in use.
Also, small tweak to lock and log removal of a SOG from the SceneObjectGroupsByLocalPartID collection in SceneGraph.GetGroupByPrim() if an inconsistency is found.
