Deleted favorite channels still exist

Observed behaviour

The deleted favorite channel remains, but shows up with a DM icon with what I think was the channel's ID number. Attempting to load it gives an error message saying "Couldn't load messages". Side note: I think on the canary desktop client this actually checks whether you have access to the channel, not whether the channel is deleted. I had favorited the canary releases channel in canary desktop testers, and while I cannot verify I believe that channel has just been hidden. Mobile app still hangs on to this now-invisible favorite, but desktop removes it entirely.

Reproduction steps

(Optional) Create a channel
Favorite it
Check that it's in your favorites menu on both desktop and mobile app
Delete the channel
