Paypal Express Checkout - Issue with paid Shipping Method.

[JonasFolletete]

Describe the bug
We have a problem with the Paypal Express checkout when using a paid shipping method
When we try to update the order with a paid delivery method, We get the following errors from the route : FR/V1/adyen/express/paypal-update-order/guest fail with the following error :

{ "message": "Error with payment method, please select a different payment method." }

In the Magento log we have the following error :

AdyenLoggerTest.INFO: Response from Adyen API {"body":{"error":"Sum of selected deliveryMethod amount and original offer amount does not match the total amount.","errorCode":"14_0478"}} {"uid":"XXX"}

We don't have any issue if we use a free shipping method.

To Reproduce
Steps to reproduce the behavior:

1. Go to product page
2. Click on paypal express checkout
3. Select paid shipping method
4. Paypal show the error "Unable to update address. Please try again"

Expected behavior
Price should update according to the shipping method selected.
