**Current behavior:**
Creating an ewallet loyalty program and removing the default
value for `trigger_product_ids` without adding another in its
place will result in any ewallet created using that program to
not have its balance deducted after being used in a sale order.
**Expected behavior:**
The default product should not be required here, nor should any
product, seeing as there is no `required` constraint on this
field nor any related ones.
**Steps to reproduce:**
1. Create an ewallet loyalty program and remove the Top-up
ewallet product
2. Create an ewallet, give it some balance, and use it in an
order
3. Check the balance of the wallet to see the erroneous behavior
**Cause of the issue:**
In the _program_check_compute_points() method of `sale.order` in
`sale_loyalty`, the conditional block:
`if not products_per_rule.get(rule):
continue`
will normally prevent rules belonging to ewallet program types
from going further in the method because they have the default
ewallet top-up product in their domain. When the continue is not
reached, they will reach this line:
`amount_paid = sum(max(0, line.price_total) for
line in order_lines if line.product_id in rule_products)`
which will end up offsetting the actual subtraction of a SOLs
`points_cost` from an ewallet `loyalty.card`'s balance.
**Fix:**
Add another check prior to the calculation of order points which
prevents ewallet coupons without any top-up products from
reaching the problematic code. If an ewallet program doesn't
have any `trigger_product_ids`, it shouldn't ever need to
perform such calculations.
