[FIX] payment_stripe: fix bad request not displaying

Reproduce the issue

    - Install eCommerce
    - Activate stripe, use testing credentials and select
      Configuration > Payment Flow > Payment from Odoo
    - Create a contact that has a trailing whitespace at the beginning
      of the email
    - Grant him portal access, and a password
    - Open your browser devtools
    - Login to the web shop with this portal user and buy an item using
      stripe

    1. Error Dialog: Server Error (HTTP 500)
    2. The exception received by the front-end is not clear
    3. When the 500 error is fixed, we still have a error dialog
       => bad UX

Cause

    1. The raise was removed but we need to keep it because
       it allows the true error to be raised (bad request)

    2. The "invalid email address: x" is lost when we raise the
       exception

    3. In V13, all catch & guardedCatch open a error dialog if we
       don't set preventDefaulted to true on the error's event

This commit changes restore the raise, change the error message and
disable the error dialog for this case.
