Use a dataset's name to fetch it's metadata from RDF

* gn3/api/metadata.py (jsonify_dataset_metadata): Rewrite metadata
end-point to use a dataset's name instead of it's accession_id.
* gn3/db/rdf.py (get_dataset_metadata): Replace accession_id with
name.  Use one single RDF query instead of multiple queries.
