    ipatests: adapt for new automembership fixup behavior
    
    The automembership fixup task now needs to be called
    with --cleanup argument when the user expects automember
    to remove user/hosts from automember groups.
    Update the test to call create a cleanup task equivalent to
    dsconf plugin automember fixup --cleanup
    when it is needed.
