…onstraint conflicts

The `product_variant_default_code` module adds a unique constraint, which causes test failures when installed alongside `sale_pricelist_global_rule`. This fix adjusts the tests in to avoid conflicts with this unique constraint, ensuring compatibility when both modules are installed.

If not, we get:

```
Traceback (most recent call last):
  File "/opt/odoo/custom/src/odoo/odoo/http.py", line 658, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)

    raise exception.with_traceback(None) from new_cause

psycopg2.errors.DatatypeMismatch: ARRAY types integer and boolean cannot be matched

LINE 9: ...L OR item.global_product_tmpl_id = any(ARRAY[false,...
```

A little refactor for better code in the method is also done.

complementary to commit 637c766

- Reused Odoo's base code for computing pricelists, adapted it to new functions, and simplified the logic.
- Renamed selection options for the applied_on field: 4_global_product_template to 3_1_global_product_template and 5_global_product_category to 3_2_global_product_category to ensure the correct order in pricelist items.
- Fixed an assertion in the tests. Previously, changing the UoM did not update the price, but this behavior was introduced in PR OCA#2473.
- Added a new assertion for the pricelist_item_id field.

Issue introduced in OCA#3150
