[FIX] website_sale: invoice and delivery address

Create the following
- Create a partner of type "Company" (Address 1)
- Add an "Invoicing" address to this partner (Address 2)
- Add a "Contact" address to this partner
- Authorize this contact as a portal user

Connect as the portal user created:
- Place an order from website, add a product to cart
- In "Shipping & Billing", confirm the order. The proposed billing
  address is "Address 1". Do not change the shipping address ("Ship to
  the same address"), and confirm.

The "Bill To" as well as the "Ship To" address are set to "Address 1".
This is a regression from v8. In v8, "Bill To" is set to "Address 2",
while "Ship To" is set to "Address 1".
