Subject: [PATCH] [FIX] warning: fix override of product_id_change

Without the @api.multi property,
the method is considered as taking only one parameter (self?),
while it takes multiple parameters.

This prevented to change the quote template on a sale order,
if the quote template had some order lines, due to the below error

`TypeError: product_id_change() takes exactly 1 argument (19 given)`
