Fix rotation gizmo for empty Spatials

Browse Source 
The AABB for an empty Spatial has 0 size, since the stored and
compared Transform was scaled by the AABB size, it would completely
destroy the rotation information. If there is no rotation
information, the gizmo doesn't update when the rotation changes.
