[FIX] payment_stripe: disable button

- Create an order from the eCommerce
- Choose to pay with Stripe
- Enter the credit card info, validate

There is a short window of time (before the reload of the page) where
the user can click on 'Pay Now' again.

This is because the HTML is completely replaced, including the button.
We restore it when necessary.
