Running tasks do not work from the root of the engine

[rreinhardt9]

While developing on the engine, you should be able to run rake tasks like rake db:migrate and rake db:setup from the root of the engine. Currently, you cannot and it returns an error that states it could not find the location of the Rakefile:

$ bundle exec rake
rake aborted!
