Cannot log out (stuck on key backup dialog)

### Steps to reproduce

A preliminary step may be to start a new DM conversation with someone new.

1. Start logging out of an account
2. See the dialog warning me "You'll lose access to your encrypted messages"
3. Click the right button to "Connect this session to Key Backup" (I'm not sure what that actually means)
4. See spinner and then same dialog again
5. Click "Connect this session to Key Backup"
6. See "Keys restored" dialog (confusing as I was backing up keys, not restoring them)
7. Click "OK"
8. Dialog closes but I'm still logged in

### Outcome

#### What did you expect?
To be logged out

#### What happened instead?
I can't log out unless I press a scary button saying that I will lose my keys
