Describe the bug and add screenshots

There was a communication problem between paypal and PrestaShop through the webhooks that raised exceptions. The final behavior was expected.

The following exceptions occurred:

The order detail in Prestashop show the communication details and seem normal:

Expected behavior

No exception should be raised.

Steps to reproduce

We are tracing exceptions with sentry, this is how we noticed the exception happening.

1. In the BO, open an order payed with paypal
2. Choose the order state "Remboursé" (Reimbursed), click "Mettre à jour l'état" (Update order state)
3. There is a message telling that the order will be refunded in paypal, and that PrestaShop is waiting for the confirmation from paypal
4. The order was Reimbursed in Paypay and in Prestashop, so form the user perspective everything worked as expected.
