ListNodeIndexes return value when neo4j has no index.

Hey,

Just wondering about listAllIndexes behavior when the GraphDB has no index. Got this error when calling listNodeIndexes:

throw err;
         ^
Error: HTTP Error 204 when listing all indexes.
    at ~/dev/mappingsMMtest/node_modules/node-neo4j/main.js:455:14

Is it something that should be handled by Neo4j ? Is there a reason for this ? Would returning an empty object, "false" or anything that would inform the user that no content was found be better than causing this error ?

If yes, I would be happy to change the listIndexes method and make a pull request.
