fix: leave NSFW channels out of the categories and sources playlists

The other public generators drop NSFW streams with isSFW(), as PLAYLISTS.md promises (no NSFW channels since January 30th, 2024), but categories/ and sources/ took every stream, so NSFW channels with a feed were published there. The test fixture's NSFW channel now carries its feed id, so it reaches the generators instead of being dropped as a stream without a feed.
