This will merge the source scene into the destinationScene.
This function merges the contents of the source scene into the destination scene, and
deletes the source scene. All GameObjects at the root of the source scene are moved to the
root of the destination scene.
NOTE: This function is destructive: The source scene will be destroyed once the merge has
been completed.
