0037096: [RR17Q4] [Digital Coupons] Payments aren't deposited to the correct account after editting it for the Issuing Company

Description

When paying a receipt with a Digital Coupon whose accounting has been edited from the Issuing Company window,
the Payment In record generated from it will always be deposited to the account the coupon was originally
set to.
In other words, the changes aren't correctly applied in the Accounts tab of the Issuing Company window, which
leads to an inconsistent behavior.

Steps To Reproduce

With the Digital Coupons for Retail module installed...

There are to ways to execute these steps:
-- 1st alternative: Create a receipt before and after editing the "Financial Account" field --
- Execute steps 0 to 9. In step 9, the "Deposit Field" shows "Voucher - Vall Blanca Store - EUR", which is correct
- Modify the "Financial Account" field in step 2 to "Chèque Gourmet - Vall Blanca Store"
- Execute the rest of the steps, 4 to 9
-- 2nd alternative: Create a receipt after editing the "Financial Account" field --
- Execute steps 0 to 3
- Modify the "Financial Account" field in step 2 to "Chèque Gourmet - Vall Blanca Store"
- Execute the rest of the steps, 4 to 9
