Fix script state not being preserved in objects sent via Hypergrid.

This was because attributes were not being included in the transformation, hence losing the script state identity.
Symptoms are messages like "[SCENE OBJECT GROUP]: SavedScriptState element had no UUID in object test box"
Regression since the conference code merge.  Regression test extended for this case.
