Parses a triple and updates the Neo4jTriple object is language-insensitive

[edelabreu]

Please consider updating the parse_triple function in the Neo4jTriple class. This function doesn't take into account the language properties of the object it's assigned to in a configuration like this.

config = Neo4jStoreConfig(auth_data=auth_data,
                          handle_vocab_uri_strategy= HANDLE_VOCAB_URI_STRATEGY.MAP,
                          handle_multival_strategy= HANDLE_MULTIVAL_STRATEGY.ARRAY,
                          multival_props_names=[("skos","prefLabel"), ("skos","altLabel")],
                          batching=True)

I made this code modification to correct this.
