fix(SDK): ensure simulator hand rotation is on top level controller
fix(SDK): ensure simulator hand rotation is on top level controller

top level controller object rather than the hand model as the top
level controller object is what rotates in other SDKs and the scripts
rely on that rotation (such as the pointer scripts).
