The problem that this test ensures rdflib solves is that, previous to PR #1108, the
parsing of two triples with the same n-triples Blank Nodes IDs, here _:0, would
result in triples with the same rdflib internal BN IDs, e.g.
rdflib.term.BNode('Ne3fd8261b37741fca22d502483d88964'), see the Issue #980. They
should have different IDs.
