[IMP] website_sale: stop showing variant option when not active

Since this commit [1], we don't want to display the "List View of
Variants" option on the product page if option "Variants" in settings
was disabled. Now that the customize show menu options have become
snippet options in edit mode, the code to do this has been adapted.
