When setting another state as default, the ex-default one gets executed out of order.

Repro:
1. Add 2 states (one default), and add motions to them
2. Make transitions from Entry to Default to state2 to exit
3. Play the scene - it works fine (default then state2 is being executed)
4. Exit play mode. Make the the state2 a default state
5. Play again - the ex-default state is still being execute even though there is no transition leading into it.

Expected: the ex-default state gets ignored
