Changing order status from complete to 'pending payment' doesn't update appointment status

[Valentina R]

To reproduce mark an order complete and appointment status goes to complete.

Now change the order status to 'pending payment' or 'on-hold' and status of appointment doesn't change. It should go 'unpaid'.
