'log out' button not working

[kvanderkamp]

Expected behavior
Clicking the 'log out' button, then clicking 'OK' in the verification prompt, logs out the Discord user from the game.

Actual behavior
Discord user remains logged in and related functionality in game remains usable.

Reproduction steps

1. Go to https://physics.zemanzo.nl/client
2. Log in using Discord
3. Click 'log out'
4. Press 'OK' in the verification prompt
5. User remains logged in.

Additional context
I have joined the 'Manzo's Marbles' Discord server with the same account I am using for web-marbles.
