Add transform-react-jsx-source to react-native preset 

Summary:
Putting this up as request for comments.

The PR adds [transform-react-jsx-source](https://github.com/babel/babel/tree/master/packages/babel-plugin-transform-react-jsx-source) to the list of plugins that come by default with the `react-native` preset. It will enable the use of a bunch of really cool tooling around JSX, however those are generally useful only in development mode. Is changing `react-native` preset the right thing to do in this case? Is there a way to enable this transform only in DEV? Should I add this somewhere else?
Closes https://github.com/facebook/react-native/pull/6351
