Neo4j Server doesn't connect to embedded database in Rails - ruby-on-rails

Question

I'm trying to get a Neo4j server connected to a database embedded in a Rails project. I'm following this guide: https://github.com/andreasronge/neo4j/wiki/Neo4j%3A%3Aha-cluster The only thing different, I think, is that I'm using the 1.9.7 Neo4j community server. I am able to start the rails server and the rails console, and both work simultaneously. I can start the standalone server just fine, but I can only see the root node in the UI.
I tried to point the standalone server to one of the two embedded databases, but the server then updates the database such that the Rails application doesn't start anymore.
Please let me know if you need more specifics.
Any hints are welcome. Thanks.
Here's the standalone server's neo4j.properties
ha.server_id=3
ha.initial_hosts=localhost:5001,localhost:5002,localhost:5003
ha.server=localhost:6003
ha.cluster_server=localhost:5003
ha.pull_interval=1
allow_store_upgrade=false
keep_logical_logs=true
Here's the standalone server's neo4j-server.properties
org.neo4j.server.database.location=data/graph.db
org.neo4j.server.database.mode=HA
org.neo4j.server.webserver.port=7474
org.neo4j.server.webserver.https.enabled=true
org.neo4j.server.webserver.https.port=7473
org.neo4j.server.webserver.https.cert.location=conf/ssl/snakeoil.cert
org.neo4j.server.webserver.https.key.location=conf/ssl/snakeoil.key
org.neo4j.server.webserver.https.keystore.location=data/keystore
org.neo4j.server.webadmin.rrdb.location=data/rrd
org.neo4j.server.webadmin.data.uri=/db/data/
org.neo4j.server.webadmin.management.uri=/db/manage/
org.neo4j.server.db.tuning.properties=conf/neo4j.properties
org.neo4j.server.manage.console_engines=gremlin, shell
org.neo4j.server.http.log.enabled=false
org.neo4j.server.http.log.config=conf/neo4j-http-logging.xml
These are the Noe4j and Rails related gems included in my Gemfile:
gem 'rails', '3.2.13'
gem 'neo4j', '>= 2.2.3'
gem 'neo4j-community', '1.9'
gem 'neo4j-advanced', '1.9'
gem 'neo4j-enterprise', '1.9'
In config/application.rb I added:
require "neo4j/rails/ha_console/railtie" if Rails.env.development?
config.neo4j.storage_path = "#{config.root}/db/neo4j-#{Rails.env}" unless Rails.env.development?
When I start the rails server:
