Do not delete exclusion's list website if enabled by publisherToggle

[cezaraugusto]

Fix #9938

This allows websites from exclusion list to be visible if the user decides to. Usually, excluded-list websites aren't included but the user can opt-in by hitting the publisherToggle.

Test plan:

1. Enable payments;
2. Go to a verified website;
3. Website should be visible in payments;
4. Toggle on/off;
5. works, site is not excluded;
6. Go to an unverified website (not in the exclusion list), like wired.com;
7. Hit the publisherToggle;
8. Website should be visible in payments;
9. Toggle on/off;
10. works, site is not excluded;
    (now the bug that this PR fixes)
11. Go to an excluded website (google, brave, netflix)
12. keep navigating in the website up to a point that it should match minimal visibility criteria;
13. Website should not be visible in payments;
14. Back to website, hit publisherToggle
15. Website should be visible in payments;
16. Toggle on/off;
17. works, site is not excluded;
18. Exclude a website by hitting the trash icon inside payments;
19. Should not be visible;
20. Go to wheel icon and disable payments for non-verified;
21. Only verified websites should be visible
