[FIX] website_sale: _cart_update
[FIX] website_sale: _cart_update

The price of the product was not updated according to the pricelist
when changing the qty of a product in the cart because the context
of the product was not correctly set before calling function
_get_display_price in _cart_update.

But this part of code seems to be redundant with _website_product_id_change.
