Factories don't generate to rspec/ when :suffix option used

[eric-hu]

My pull request (#78) introduces a bug when the :suffix option is combined with Rspec. Factories are generated in test/ instead of spec/

$ rails g model model_name
  invoke  active_record
  create    db/migrate/20121210203814_create_model_names.rb
  create    app/models/model_name.rb
  invoke    rspec
  create      spec/models/model_name_spec.rb
  invoke      factory_girl
  create        test/factories/model_names_factory.rb

I'll submit another pull request when I can track down and fix why this is happening

Not sure why the previous PR didn't close this, but FGR gem v4.2.1 should have resolved this. Thanks @eric-hu!
