[FIX] sale_product_configurator: use product with archived variant

In a sale order, an error is raised when selecting a product
(`product.template`) that has an archived variant if the product has a
single active attribute

Steps to reproduce:
1. Install Sales
2. Create a new product 'TEST'
3. Add the attribute 'Legs' with values 'Steel' and 'Aluminium'
4. Create a new sale order for any customer with product 'TEST' and
   variant 'Steel' and confirm it
5. Open the form of product 'TEST', remove the attribute 'Legs' and add
   the attribute 'Color' with values 'White' and 'Black'
6. Create a new sale order and try to add the product 'TEST', an error
   is raised

Solution:
Exclude `product.template.attribute.value` from the ptavList only if it
is present in the ptavList

Problem:
If a product has an archived variant that uses the same attributes than
an existing active variants except one, we will try to exclude the
different attribute but because it has been archived, it is not present
and cannot be excluded.
