Fix the issue of not removing node in old scene when switching scenes. - When a timeline is playing and crossing two scenes (tween block), nodes, for the old scene, in duplicate group must be removed. But, it is not. - It is fixed by checking if nodes, in the duplicate group, are also in the key frame next to the new scene. All nodes that is not in next key frame are remove.
