Test film_grain_params_ref_idx is in ref_frame_idx

Section 6.8.20 (Film grain params semantics) of the spec has the
following requirement:

  It is a requirement of bitstream conformance that
  film_grain_params_ref_idx is equal to ref_frame_idx[ j ] for some
  value of j in the range 0 to REFS_PER_FRAME - 1.

    Note: This requirement means that film grain can only be predicted
    from the frames that the current frame is using as reference frames.
