[gimp] Use gimp_item_get_container_iter() instead of the GimpImage iter APIs

[Michael Natterer <mitch src gnome org>]

commit 603d3441e786834ef57f1bbd90c8dd5ba148e38f

    Use gimp_item_get_container_iter() instead of the GimpImage iter APIs
    
    Using the new function makes sure the sensitivity of the raise and
    lower actions corresponds to what is possible (raising and lowering
    within the group).
