    initialSetup: Fix quit action
    
    We will currently always open the main application window after the
    initial setup window has been closed. This behavior is correct if
    the window was completed or dismissed, but not when the app itself
    was quit - cancel continuing to the main window in that case to
    get the expected behavior.
