Rake task tries to load file that has been removed from the project

hi,

When trying to run bundle exec rake neo4j:migrate in a project that is not Rails, I get the following error:

rake aborted!
LoadError: cannot load such file -- active_graph/session_manager

Looking at the Rake task code, I can see that it's requiring this active_graph/session_manager file: https://github.com/neo4jrb/activegraph/blob/master/lib/active_graph/tasks/migration.rake#L8

However the file seems to have been removed from the project, I can't find it in https://github.com/neo4jrb/activegraph/blob/master/lib/active_graph

Runtime information:

Using activegraph 10.0.1, but it looks like master has the same problem.
