[FIX] product: variant exclusion not taken into account

Steps to repoduce:
- Go to Sales - products
- Create a product
- Add variants (3 attributes and 2 values each) Total is 8 variants.
- onfigure variants: Select 1 attribute and exclude it for 1 variant (for example: exclude for size 12x12)
-> the number of variants remains at 8. The one that is excluded is still visible in the Product variants tab.

Solution:
When an exclusion is created, archive all the not-possible-combination.
