Fix compare-frame-indices option in rdf validate

[adanilenka]

Given: a valid jelly file with 3 frames.

Sample input (end of frames marked for the multi-file split, if necessary):

<http://example.org/resource/r1> <http://example.org/property/p1> <http://example.org/resource/r2> .
<http://example.org/resource/r3> <http://example.org/property/p2> <http://example.org/resource/r4> .

_:b1 <http://example.org/property/p4> "2000"^^<http://www.w3.org/2001/XMLSchema#integer> .
_:b1 <http://example.org/property/p3> "0.009"^^<http://www.w3.org/2001/XMLSchema#float> . ///end of frame 1

<http://example.org/resource/r1>  <http://example.org/property/p4> "100"^^<http://www.w3.org/2001/XMLSchema#integer> .
<http://example.org/resource/r2>  <http://example.org/property/p3> "90"^^<http://www.w3.org/2001/XMLSchema#integer> .
<http://example.org/resource/r3>  <http://example.org/property/p4> "0.1"^^<http://www.w3.org/2001/XMLSchema#float> .

<http://example.org/resource/r5> <http://example.org/property/p5> <http://example.org/resource/r7> .
<http://example.org/resource/r6> <http://example.org/property/p6> <http://example.org/resource/r8> .
<http://example.org/resource/r9> <http://example.org/property/p7> <http://example.org/resource/r10> .  ///end of frame 2

<http://example.org/resource/r2>  <http://example.org/property/p1>  <http://example.org/resource/r3> .

Query to generate the respective .jelly file from one input file above:
jelly-cli rdf to-jelly ./in.nt --to ./in.jelly --opt.generalized-statements=true --opt.rdf-star=false --opt.max-name-table-size=8 --opt.max-prefix-table-size=0 --opt.max-datatype-table-size=4 --rows_per_frame=14

for frame 0, the rdf validate command works with no issues:
jelly-cli rdf validate ./in.jelly --compare-to-rdf-file ./out_001.nt --compare-frame-indices=0 --compare-ordered --delimited='true'

for frame 1, using
jelly-cli rdf validate ./in.jelly --compare-to-rdf-file ./out_002.nt --compare-frame-indices=1 --compare-ordered --delimited='true' --debug results in

Duplicating stream options in the beginning of the second frame leads to:
