Rework SPARQL test suite

This patch reworks the SPARQL test suite to use the new DAWG manifest processor. The actual checker is also more accurate, correctly reporting negative tests and more correctly checking the resutls of positive tests. There are still some tests from the SPARQL test suite that are not executed, but checkers for these will be implemented later. Other changes: - Fixed `test/data/suites/rdflib/sparql/unicode.srx`. This file did not have the correct content for the query. I verified this with Apache Jena.
