Upgrading to neo4j.rb 8.0 and neo4j-core 7.0.0 breaks Devise code about devise-activegraph

Hey @Grace thanks for the report! I'm actually cleaning up a bit of stuff in this gem right now, so I'll have a look at this shortly!

I've looked a bit and I'm wondering what version of Neo4j are you using?

It seems that this is failing in the place where version 8.0 of the neo4j gem is trying to figure out what constraints are in the database so that it can validate that your app has the constraints it needs. I'm wondering if the version of your Neo4j database is affecting the response from db/data/schema/constraint

I think I've fixed this (or at least made it better). There was an issue where Neo4j was returning an error when the gem was trying to get constraints or indexes which was simply causing the gem's code to trip up. That error should now be raised as an exception. Try running:

bundle update neo4j neo4j-core

At that point you should get a CypherSession::ConnectionFailedError exception with more information from Neo4j on what is wrong
