[FIX] website(_sale): allow to use and access website pricelist

Before this commit, if the website's company was different than the user
company, the ecommerce would use the user's company instead of its own
pricelists.

Step to reproduce:
  - Set company2 to website1
  - Create a pricelist1 for company1 and a pricelist2 for company2
  - With an user from company1, visit the website1.
  - The pricelist used will be the one from the user, pricelist1 and not the
    pricelist2 from company2 which is the website1 company.
