[FIX] product, sale, stock: remove deleted product from demo data

Current behaviour:
When installing Sales, then PoS, we get an error when loading the modules.

Expected behaviour:
No error should be present when installing PoS just after the Sales app.

Steps to reproduce:
(With demo data)
- Install Sales
- Install PoS
- Get Error

Reason for the problem:
When installing Sales, there is the Product dependency that creates a product variant,
named product_product_4d.
Then in the Sales demo data there is the addition of an "exclude_for"
record (basically an exclusivity rule for variant attributes, for ex: A AND B cannot be together).
In our case it happens to be the attributes which product_product_4d was based of. Therefor the ORM
deletes said record (from the database).
Then when installing PoS, it installs Stock as a dependency, which demo data references product_product_4d,
which is not present anymore in the database.

Fix:
Remove the creation of product_product_4d and all the records that reference it.

Affected versions:
