Before this commit: 1. With a coupon set on 'specific_product', the discount amount was multiplied by the product quantity twice. (Introduced by a42c27f which apply discount on the full price by using price_total (already multiplied by quantity) over price_unit. 2. With a coupon set on 'cheapest_product', the discount was not discounting taxes. 3. With a coupon set on 'cheapest_product' and `sale_coupon_delivery` installed, it would simply crashes and throws an error since `sale.order.line` has no `program_id` attribute. Now: 1. We no longer multiply by the quantity twice; 2. We apply discount on the full price (with taxes); 3. We use correct attribute to avoid crash. opw-1830986
