Noray instance ECONNRESET when shutting a connected game via the editor stop button

[Learus]

Hey there.
A possible bug I noticed:

1. Run the game via the Godot Editor
2. Connect to noray (I do it automatically for now)
3. Shut the game down using the Stop button in the editor
4. Noray server crashes with ECONNRESET.

If I shut down the game normally (by get_tree().quit(), or by pressing the X button on the main window) everything is fine.

For now, it's not a big issue for dev, because I could just "restart: always" the dev noray server. Nevertheless, it could cause problems in the future.

#55 added some more error handlers, which might fix this. Will test again once that's merged.
