uTox doesn't save proxy settings

[meyou69]

Overview

1. uTox version: 0.18.1
2. Operating system: Fedora 34
3. Desktop Environment/Window Manager (Linux/BSD only): KDE Plasma

Issue

When setting a SOCKS 5 proxy in the Advanced tab (Address 127.0.0.1 and port 9150) in uTox, enabling the proxy and then immediately exiting uTox from the status icon in the system tray, I re-open uTox afterwards and go back to the Advanced tab and find that the IP address and the port in the SOCKS 5 configuration are empty again.
Upon exit, I would expect for uTox to save the configuration for the proxy address and port so that I wouldn't have to configure them each and every single time I open uTox. This feels like a bug

I was able to reproduce the bug. It seems that exit from system tray does not save the settings, while closing the window regularly does. Thanks!
