[FIX] website_sale: multi-company payment methods

Steps to reproduce:
- Have a portal user with a related contact (thus on the contact, partner_share is True)
- Set a default company A on the user, and the same company A on the sales tab on the contact (so the company_id field is A)
- Have a website linked to company B
- Connect to said website with the portal user
- Try to buy something

Issue:
Internal error - Multi company issue

Solution:
It is mainly a configuration error but the message is not user firendly.
Instead we make sure the partner cn proceed a transaction in the company website
