UNO!: reset must_play when changing turn

After a successful challenge, the challenged player can choose to
pick&pass instead of playing one of its allowed cards. In such a case,
the must_play array would not get reset, preventing the next player to
be able to play any of its card.

Fix by resetting must_play on next_turn rather than on set_discard.
