Fix tests.

The new RDF converter revealed several issues with our existing tests,
which are fixed here.

* test_convert.py (test_to_rdf_hydrated): That test used an incorrect
  "NOT" value for a predicate modifier slot (the correct value is "Not",
  and there is nothing in the spec to suggest it is case-insensitive);
  it also forgot to declare some prefixes;

* test_writers.py (test_rdflib_endpoint): That test used
  "sssom:MappingCuration" as a column name in a MappingSetDataFrame,
  instead of the expected "mapping_justification"; it also forgot to
  declare some prefixes.
