[FIX] pos_adyen: Retry automatically to get last status

When making a payment intent from Adyen terminal with the POS, the payment intent was validated by Adyen
but Odoo stopped polling because a connection failure happened.

With this fix we use the remaining_polls already implemented to get the adyen status with a interval of 3 secondes.
If after 3 tries of 3 seconds each it still fails we can retry manually.
