Favorites do not get removed completely

[TommyTran732]

Brief summary

After a manga has been removed from favorites, it continues to show up in search. I cannot seem to find a way to remove it completely.

Another thing I noticed is that after a source has had all of its favorites removed, it still shows up in the filter.

Clearing cache in both the app and from Android settings does not resolve the issue.

Both of these suggest that favorites data still remains somewhere in the app's internal storage and doesn't get cleared properly.

Steps to reproduce

1. Add a manga to favorites
2. Remove the manga
3. Observe the behavior described

Kotatsu version
