deleted sites from muon are not being imported to Rewards - follow up to PR 736

[LaurenWags]

Description

Found while testing brave/brave-core#736

Per test plan in brave/brave-core#736, Deleted sites from muon should be imported as 'excluded' sites in Brave Rewards.

Steps to Reproduce

Follow test plan in brave/brave-core#736 or

1. Have a muon Brave profile set up with 0.25.2 where you have Payments data (wallet, etc). Have some sites in table, delete some others.
2. Close muon Brave.
3. Ensure you don’t have any Brave-Browser profile for b-c Brave.
4. Launch 0.57.12.
5. Import only Payments data from Brave (Brave > Import Bookmarks and Settings > choose Brave (old) > only have Payments checked
6. Navigate to 6 sites.

Actual result:

When you open the popup to view all sites, no link for restoring excluded sites. You can also try visiting a site that you know was excluded in muon. --> Watch it get added to your A-C table after specified time from settings. Alternatively, I clicked on the BAT logo and saw that the toggle for ‘Include in Auto-Contribute’ for this site was set to On.

Expected result:

Deleted sites from muon Payments should be 'excluded' in Rewards.

Closing as wontfix after discussion on Slack. Let's re-open if this should indeed block the release (and needs a fix)
