    Remember last used camera
    
    During setup_camera() in cheese-application.vala, we were not explicitly
    assigning the camera from settings and only assigning the camera from
    the command line.
    
    This now checks for values from both the command line and from settings
    and allows the command line to override settings.
    
    Fixes: https://gitlab.gnome.org/GNOME/cheese/-/issues/76
