ActiveGraph exception prevents single tests from running.

[knirirr]

In a Rails 7.1.3 application with activegraph-f86d54c8ebf6, neo4j-ruby-driver-4.4.5, and Neo4j 4.1.6 the test_helper file contains require 'active_graph'. Running all the tests with rake test is fine, but running single test with e.g. rails test test/models/example_model.rb will throw the following exception:

~/.rvm/gems/ruby-3.2.2@my_app/bundler/gems/activegraph-f86d54c8ebf6/lib/active_graph.rb:32:in `<main>': uninitialized constant ActiveGraph (NameError)

Neo4j::Driver::Result.prepend ActiveGraph::Core::Result

This appears to originate from the require call in test_helper.
