[FIX] product: sort attributes before checking existing variants

When generating the list of all needed variants, the attributes are sorted based
on the order in field attribute_line_ids while, when comparing with existing
variants, the order of the attributes on the product.product is the order
on the field attribute_value_ids. As both order could be different (no direct
relation), variants could be wrongly recreated instead of keeping existing one.

Make sure the attribute lists are always sorted.

Fixes #4361
