Update neo4jTest DB

If changes are made to functionalities of any of the clients, the corresponding patient files, used for the unit tests also need to be changed. The neo4jTest db is non-volatile and it loads from the neo4jTest present locally everytime the containers are up. This is to maintain consistency in the files that are being tested.

To update the neo4jTest db. First, clear the existing graphs in the db through the web UI. Then, check if no nodes exist. Then create all the necessary chains needed. Then, copy the neo4jTest/data volume to your local system. Delete the older neo4jTest db folder. Use the latest one to load the volume into the neo4jTest container. Tar the latest db before committing it.
