Reusing NamespaceManager.normalizeUri for transforming Graph to DataFrame.
In effect we only need to strip < and > from N3 representation and
forget the case of URIRef being a rdflib.term.Variable.
Parameters
----------
namespace_manager : rdflib.namespace.NamespaceManager
NamespaceManager to use to normalize URIs
uriref : rdflib.URIRef
URI to normalize
Returns
-------
str
Normalised URI string.
