Fix the rdf:type of a couple of the Turtle syntax tests

[kal]

Tests 'nt-ttl-star-4' and 'nt-ttl-star-5' should both be typed as 'rdft:TestTurtlePositiveSyntax' rather than 'rdft:TestNTriplesPositiveSyntax' in the Turtle syntax test suite.

@pchampin -- this is a small bug fix. It has no copyright or patent implications. Do we need the IPR test to pass? Can I mark it "non-substantive"?

@kal - explanation - we are operating as part of the RDF-DEV CG. The contributions checking process is slanted towards content for the documents where people submit under the W3C IP declaration for CGs.

pchampin marked as non substantive for IPR from ash-nazg.

@kal - thanks!
