    Prevent hanging in DELETE_IN_PROGRESS

    When during update one resource is deleted and another independent
    resource takes long to update itself, deleting such stack when it is
    UPDATE_IN_PROGRESS led to a stack being stuck in DELETE_IN_PROGRESS as
    deleting backup stack was not finding the already deleted resource.
