[14.0][FIX] sale_commission_product_criteria: Get items without commission

[SirPyTech]

Backporting 2 small PRs from 16.0: #615 and #619.
@Tisho99, @ValentinVinagre and @manuelregidor thanks for your work on those PRs!
Maybe you want to have a look?

I have also a dded a fix for method _get_commission_items: unfortunately I don't know ho to reproduce it from the UI, but calling the method with an empty commission raises:

ERROR: operator does not exist: integer = boolean
LINE 9:             AND (item.commission_id = false)
                                            ^
HINT:  No operator matches the given name and argument types. You might need to add explicit type casts

See the added test for more details.

Thanks for the review!
I usually don't add it because it feels redundant, but here I added it to thank you for the approval 😉

Thanks for the feedback anyway 🤗
Sorry for the noise, as you know it's hard to get reviews in the OCA so I usually ping whoever might be interested.

No problem 😸 . You should ping the repository's psc's; they're the ones who maintain the whole ecosystem.

I usually bother the PSC only when the PR has enough reviews.
