Fix resource shared when duplicating an instanced scene

Browse source 
For resources with `resource_local_to_scene` enabled in the sub-scene,
the resource is already set when the sub-scene is instantiated, so does
not need to be set again. Just needs to update the property of the
resource according to the value in the main scene.
