Description
When a RigidBody is removed inside notifyOnContact the game crashes. This happens because the PhysicsWorld still runs lateUpdate. Adding an if (rb != null) inside the for loop here fixes the issue, but I don't know if that's the proper solution.

To Reproduce

1. Add a Haxe trait to a RigidBody
2. Add object.remove() inside the RigidBody.notifyOnContact notifier

Expected behavior
To remove an object containing a RigidBody from notifyOnContact without errors.
