Graph is duplicating expanding nodes #30
Description
While connected to a Neo4J endpoint and when double-clicking a node, the graph is duplicating the expanded node, instead of connecting children nodes directly to existent node.
In this example, I had a single node returned by initial query, and when double clicked this node, the graph is updated with a new node with the children nodes, instead of connecting the relations to the existent, double-clicked node.
Just to be clear: in the example it works fine, but when connected to a real Neo4J server, this happens.
Just created a fork, will be proposing a PR soon.
