IRC user info/away status doesn't always update

1. Enable away-on-detach for an identity

• Tested on a server with away-notify capability, but that might not be required

2. Disconnect all clients from Quassel core so auto-away is set
3. Connect with QuasselDroid-NG
4. Open a channel, open the right sidebar for user list
5. Tap your nickname to view User details

Expected

Auto-away message is cleared, as shown in Quassel desktop.

Actual

Auto-away is still shown.

Additional

The away state for other users appears to get out of sync, too. I'm not sure if this is just the User details screen and user list, or QuasselDroid not getting the user info state correctly, as it seems to happen at random.

For at least some nicks, an active PM properly shows away status, so it's likely to do with channel sidebar/User details.
