    Fix typos in container_images_prepare failure task names

    The message tasks in case of failures should reference the task to
    prepare the container images itself. In the case of create_plan, it
    would return a message for the wrong task, and in the case of
    update_plan I think it would fail altogether. This now references the
    correct task name.
