Lets say you have 2 coupons and you pass then with the URL param coupon=$value

coupon codes:

democoupon2021 - 50% (dec only)
democoupon2022 - 75% (jan only)

===== example:

• client visits url on 30 dec 2021:
  https://demo.blesta.com/order/main/packages/demoform/?group_id=2&coupon=democoupon2021

• cart updates and stores democoupon2021

• user does not check out or leaves the site.

• 5 days later the client visits:
  https://demo.blesta.com/order/main/packages/demoform/?group_id=2&coupon=democoupon2022

• expected result: old coupon removed, new coupon applied.

• actual result: invalid old coupon still in cart.
