[Vouchers] Order total in /cart page not updated

[filipefurtad0]

Description

If a voucher has been added (Step 2) and the customer checks the cart (visiting the /cart page) then the voucher parcel will appear deducting the order total. However, the order total itself, remains unchanged.

Expected Behavior

The order total should be updated on the /cart page, when a voucher has been added to the order.

Actual Behaviour

The order total is not updated on the /cart page, when a voucher has been added to the order.

Steps to Reproduce

For all voucher issues: per-requisites are:

• As super admin - enable the vouchers feature toggle
• Having a hub with at least one voucher created
• The hub should have an open shop

1. As a customer, on the shopfront, add items to the cart. Edit your cart. (pic below, point 1)
2. Begin checkout, and stop on step 2 (/payment), add a voucher to the order. Edit your cart. (pic below, point 2) -> notice the existing parcels, but see the order total was not updated ❌
3. Proceed to /summary. Notice the existing parcels, and see that order total was updated ✔️
