[FIX] sale: sale_tour selector fix

Steps to reproduce:
- install sales
- go into debug mode
- dev tools > start tour > sale_tour

Previous behavior:
tour would fail to see that the product has been selected
and time out if you do it multiple time

Current behavior:
the tour finishes properly (even if it runs multiple times)
