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.
