    _extract_amp_image_id_by_tag should return last created image

    _extract_amp_image_id_by_tag should always return the last created
    image_id, with the amp_image_tag ("amphora" by default), but it won't.

    For the sort='created_at' to work, we should use 'desc' as sorting
    direction and take the first element from the images list.

    In addition, we now limit the length of the returned images list to 2.
    The reason is that we don't need the whole list in order to warn the
    system administrator that more than one image has the amp_image_tag.
