Request: Add `id_property` to the returned rels when exporting query results

(Related to https://github.com/neo4jrb/neo4j-core/issues/318 )

Additional information which could be helpful if relevant to your issue:

Code example (inline, gist, or repo)

results = Neo4j::ActiveBase.current_session.query("MATCH (n)-[r]-() RETURN n, r LIMIT 3")
results.to_json

... "r":{"id":2,"type":"RELATED","properties":{},"start_node_id":0,"end_node_id":2} ...

We cannot reconstruct the relationships with the output of to_json

Runtime information:

Neo4j database version: 3.1.1 neo4j gem version: 8.0.9 neo4j-core gem version: 7.0.6

This is related to the other general issue of making the id_property just like other attributes to ActiveModel. It absolutely should be done, though I think I would consider this a symptom.
