The React Native build does not minify error messages in production, but it still needs to run the error messages transform to compile `invariant` calls to `ReactError`. To do this, I added a `noMinify` option to the Babel plugin. I also renamed it from `minify-error-messages` to the more generic `transform-error-messages`.
