Before this commit:
1. We were checking if the rewards were in the SO even if it was 'next_order'
program.
2. We were deducing the rewards quantity for 'next_order' program when checking
if we had enough products to meet the program requirements.
Now:
1. We don't verify if the reward is on the SO if the program is 'next_order'
2. We don't deduce reward quantity when checking if enough products to meet the
program requirements if the program is 'next_order'

Closes#3062
Steps to reproduce the bug:
- Create a promotion program P with a fixed amount discount
- Set a customer tax T on the discount product generated for P
- Create a SO with one line
- Apply the promotion program by clicking on "Update promotions"
Bug:
The SO line with the discount product is generated but the tax T was missing.

Commit 092200073 broke the discount computation for discount of type
fixed_amount. Indeed the appropriate method was not called anymore and such
discount type would be computed as percentage discount with default value of
10% (field default for percentage).
opw-1888484
A discount on products with different taxes will result in as many discount
lines as there is different taxes.
Before this commit, removing one of these lines would not do anything else.
Then, recomputing the coupon would regenerate/add back this line.
On e-commerce, it means you would never be able to remove the program by
deleting its reward lines if there are multiple taxes (and so multiple lines)
since it would `recompute_coupon_lines` right away, adding it back directly.
Now, this commit will ensure that removing one of these lines will also remove
the other ones coming from this program on other taxes.
It means removing a regular product will remove it's reward line that will also
now remove the other program's discount line on other taxes and ultimately will
remove the program from the SO since all the program reward lines got removed.
(It won't affect auto applied program since it will be regenerated afterward)

Previous commit fixed some bugs on `sale_coupon` (#2224).
This commit add some tests to be sure these bugs are fixed and won't appear
again.
task-1866977
Related to #2224
Before this commit:
1. With a coupon set on 'specific_product', the discount amount was multiplied
by the product quantity twice.
(Introduced by a42c27f which apply discount on the full price by using
price_total (already multiplied by quantity) over price_unit.
2. With a coupon set on 'cheapest_product', the discount was not discounting taxes.
3. With a coupon set on 'cheapest_product' and `sale_coupon_delivery` installed, it
would simply crashes and throws an error since `sale.order.line` has no
`program_id` attribute.
Now:
1. We no longer multiply by the quantity twice;
2. We apply discount on the full price (with taxes);
3. We use correct attribute to avoid crash.
