[1.1.104] Port from config.ini not used when rehosting from main menu

[Kejser Kagespiser]

When choosing to continue hosting a multiplayer game from the main menu, the game defaults to port 34197 instead of reading what port in set in the config.ini file.

Reproduction steps

Uncomment and change the port in the config.ini file.
Launch Factorio and host a multiplayer game.
Save the game and quit to main menu.
Press the Continue: Host {Name of save}
The game is now hosted with the default port of 34197


Attached is a session where I've first hosted a saved map from the main menu, then quit and hosted from Multiplayer->Host saved game.
