Calling a model's method thanks to an RPC will now always send the
web_editor context automatically, making sure the method gets the
website_id all the time, removing the need to guess the current website
(now the get_current_website method uses the context website_id if any).
Note: other routes already have the website_id via request.env.context
if they correctly set website=True (this commit also adds website=True
for scss files customization routes).
