[FIX] website_sale: show correct terms and conditions from company

Currently, on a multi-company environment with different website domains set, the terms and
conditions web page, which should be company-specific, are not correctly "pulled" if you check a SO

This was due to the website override that searched for a current_website, even if none was set on a
SO, thus setting the website url instead of the company one.
