ArcadePhysics.Body.destroy will now only add itself to the World pendingDestroy list if the world property exists. This prevents Cannot read property 'pendingDestroy' of undefined errors if you try to delete a physics body in a callback and then immediately change Scene (which tells the physics work to also delete all bodies)
