If the internet connection is down when Gajim is launched, Gajim doesn't retry connecting to the server
Real-life usecase:
- Add gajim to startup applications
- Reboot the computer
- When gajim starts, the device is still trying to connected to a WiFi AP. Thus, the connection to the XMPP server fails
- When the device has succeeded to connect to the AP, Gajim doesn't retry connecting to the XMPP server.
