Players who have not chosen a class/team are not AFK kicked

[saneshadows]

Apologies if this is the wrong place to report this bug, I'm not sure if it's because of gbans or the server playbook here.

Describe the bug
Players who join the server but do not choose a class/team are not kicked by the system for being afk. This was an issue since around May of this year, after the update to the game and the related updates to the server.

To Reproduce
Steps to reproduce the behavior:

1. As a player, join an Uncletopia server
2. After joining, do not select a team

This also applies to map changes. If the map changes and the player does not interact with the game, the server does not kick them for being afk.

Expected behavior
Players who have joined the server, but not yet chosen a class/team and are afk for long enough should be kicked to make space for players waiting to join and prevent lopsided games.

Additional context
Previously this issue was tolerable because players were automatically forced to a team on joining and could be votekicked by the team. Following changes to the server around August 30, players who join are instead left in the spectator list, so neither team can votekick them.

I'm not sure exactly whether the steps to recreate this are universally true, because I've only attempted it on an empty Uncletopia server. I don't know whether there are exceptions to the afk kick for when there is only 1 player on the server. However, I have witnessed several times players who have gone afk after joining or a map change and never being auto-kicked for being afk, for multiple maps in a row.
