Prerequisites

• I understand and accept the project's code of conduct
• I have already searched in existing issues and found no previous report of this bug.

Describe the bug and add screenshots

When a customer use a discount code in a purchase and its total amount it is higher than the total order AND the cart splits in 2 orders cause of there are products with different shippers, Prestashop does not generate a new cart rule with the amount remaining in the original cart rule. And of course Prestashop does not send an email to the customer when this occurs neither.

The option "partial use" is activated of course.

Expected behavior

That Prestashop create and send a new discount with the amount remaining of the discount when a order with products with diferent shippers is made to the customer.
As it does when the cart does not split into different orders.

Steps to reproduce

1. Create a cart rule with the "option partial" use and with and amount to discount(not percent).
2. Do an order with products with different shippers. The total price of the order must be below the discount in step 1.
3. Check in the email that Prestashop has not sent you any discount code with the reamining amount.
