[FIX] payment_ogone: set payment done with 3ds in pending mode

- When receiving a 3DS payment notification from Ingenico the payment
  transaction should be set to "pending" and not in "done".

  Then a second notification is send by Ingenico to set the
  payment.transaction to "done".
  This is the reason for accepting "pending" as a valid state on the
  feedback validation.
