[All Platforms][Playlists] Make private playlists ACTUALLY PRIVATE.

[Kitsun]

I've recently discovered that if I google my name on Spotify (which I also use on other sites, I googled it because I was curious) the playlists that are set as private appear in search results, I don't know if you can access them but still this isn't what "private" is. And I was using incognito, just saying.

That's something important to notice I think!
