[FIX] pos_adyen: Connection failure during Adyen payment

Steps to reproduce the bug:

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  and then on retry it made second payment
even if the first one was successful.

Fix:

Now after a failure, it will try to poll again the last transaction (with get_latest_adyen_status)
and set the payment as successful or cancelled based on the last response.
