[FIX] website_sale: Wrong terms and conditions in created SO

To reproduce (V12) using a fresh database with demo data:
 1. Install eCommerce and Sales
 2. Change Mitchell Admin settings so that he can see the 3 companies
 3. Go into Settings and set a distinct "Terms and Conditions" text for each companies
 4. Go the Website > Configuration, set "My website" to "Company_1" and save
 5. Go to the website shop and buy any items
 6. Find its corresponding Sale order (should be on Company_1)
=> "Terms and Conditions" used in the SO is the one of "YourCompany"

Analysis:
The terms and conditions are not specified in the SO creation,
so it runs the default value code to determine its value.
However the default code just ask to use the OdooBot company "Terms and Conditions".
