### What
Creating a swap on an order with a discount leads to an incorrect difference due.
**Scenario**
- Create a store with minimum 2 products (Prod A, Prod B)
- Create a discount that only works for Prod A
- Create an order for Prod A with the discount applied
- Create a swap between Prod A and Prod B
**Expected outcome**
We would expect the difference_due amount to come out to the sum of:
- -1 * (price of prod a - discount applied to prod a)
- price of prod b
**Actual outcome**
Instead the discount is applied across both products when calculating difference due. This results in a total that is instead the sum of:
- -1 * (price of prod a - discount applied to prod a)
- price of prod b - discount on prod b ignoring the condition
### How
Adds `line_item.adjustments` to relations in cart retrieval prior to setting the difference_due to car total
Fixes CORE-361
**What**
Naive fix to allow carts with 100% discount to be completed.
**Why**
Discount total is wrongly calculated if `items` and `items.adjustments` is not included in relations upon retrieving the cart.
**Thought**
This is yet another example of why we need to rethink and refactor totals computation to not depend on what is provided by the user.
**What**
Simplify the transaction base service.
**How**
In fact, it does not need to be template and reduce the extensibility as the type is internally enforce. Now, the type is deduced by this which can be any derived class.

**What**
