[gnome-boxes/gnome-3-4] Wait for right state before selecting new machine

    Wait for right state before selecting new machine
    
    We were trying to select the machine soon after creation without waiting
    for UI state to change to 'collection' and App.select_item() was simply
    failing since UI state was still 'wizard'.
