Fix bug from the initial poc of JOV
Fix menu creation
- creating a menu would create a 'container' menu in the DB (.create is call without website_id)
then writing on it would copy (if condition to cow) the menu with a website_id leaving the first
one as a menu container unused.
- website_menu should always have a website_id
we dont want to support the multiwebsite system that allow to have generic/specific menu
unlink/write is useless now since we always have a website_id
Make unique_path website dependent, 2 distinct website can have a page with same name
Make Sale report multiwebsite compliant
Make website_id on sale_order / account.invoice as a related stored from partner_id.
