Title: 'test_app' task failing without dev dependencies

bundle exec rake test_app was complaining about missing gems
spree_frontend and spree_backend when running inside extension.

Additionally couldn't open a rails console inside engines spec/dummy

Added developement dependencies to 'extension.gemspec' template so that
generated extensions include these dependencies
