[FIX] website_sale: Don't get error when selecting shipping method after refresh

Steps:
- Publish Standard method and Mondial relay shipping methods.
- Empty rules and countries on mondial relay shipping method.
- Go to shop, add a product and checkout.
- On the final checkout page, click on mondial relay and cancel the popup without choosing the location.
- Refresh the page.
- Click on Standard delivery then click on Mondial relay.

Issue:
We get an error(Null value of a variable) or the popup doesn't pop.

Reason:
When selecting the mondial relay method without location info, the ``SaleOrder.carrier_id`` of the order is set
but ``SaleOrder.delivery_rating_sucess`` is set to False(we didn't enter the location information). Because of that
when refreshing and calling ``_get_shop_payment_values()``, delivery line is removed from the order. Here we just
add the default delivery method.
