[BUG] 1-click connect #107
Description
Noticed this issue during #106 . After I cancelled connecting to a current subsription I tried 1-click connect and it immediately tried to connect to the same subscription as earlier. This is because of "SelectedSub" in MainScreen. It should be empty after denying a connect.
Also, when trying to load subscriptions, it immediately tried again to connect. This is because the 1-click connect variable was set to True after trying before when it should be set to False after failing to connect.
