[FIX] product: name search not ilike

- Create a product named 'toto'
- Perform a call to `name_search`:
  `self.env['product.product'].name_search('pouet', [], 'not ilike')`

Product 'toto' doesn't show up in the result list.

The domain should take into account that `default_code` can be `False`.

Note: the bug also occurs if the product is called 'trululu'.
