    radio-menu-item: Handle a !NULL group
    
    If we create a RadioMenuItem without a group, and then set a group, the
    menu item will still be set as active, which means an inconsistently
    drawn radio menu item - as the RadioMenuItem will set the active flag on
    itself, but then it won't reset it when it gets a new group.
