Steps to reproduce:
1. Create a product "My Test Product" (no attribute)
2. Create a quotation, select the "My Test Product" product and confirm the sale order
3. Go back to product and add an attribute "Size" with values "L", "XL"
4. Create another quotation, select the ""My Test Product" product => crash
We consider archived combination of attributes as forbidden combination in
the configurator, but when the archived product doesn't have any attribute,
the `archived_combination` was an empty list, which wasn't supported well
by the product configurator logic (client-side).
To quickly fix this issue, we can simply stop sending empty archived combination
(i.e. when the archived product had no attributes).
