Session is not disconnected when clicking New Game

[kaenganxt]

Describe the bug
When playing on a server and clicking new game in the pause menu, a new game is loaded but the connection to the server still stands so the client is now playing on a different state than the server.

To Reproduce
Steps to reproduce the behavior:

1. Join a CSM game
2. Click on "New game" in the pause menu

Expected behavior
The connection should be disconnected and the new game should load.

Versions
Type /version into the in-game chat and paste the version numbers here:

• Mod version: dev
• Game version: 1.16.1-f2

Additional context
This could possibly also happen on any of the other buttons in the pause menu (e.g. Load game), but was not tested yet.
