Issue with transpiled code in v2.14.0 vs v2.13.0

[ryanthemanuel]

We ran into an issue when we upgraded to v2.14.0 today that was not existing in v2.13.0. Specifically this issue was hit when running our continuous integration night watch tests against PhantomJS. We are seeing a console error: 'SyntaxError: Unexpected token '['' that maps to this line of code: https://github.com/reactjs/react-docgen/blob/d65bfc460d7274206c3208fc41518727acd5a490/src/utils/getMemberValuePath.js#L25 It appears that PhantomJS is not set up to use the new syntax for declaring objects. I'm not sure what transpiling happened in v2.13.0 that is not happening in v2.14.0, but there is definitely something different between the two.

da97fc6 made a change to use preset-env with Node v4 as target (instead preset-es2015). Sorry for that! We could switch back, but of course we to transpile as few code as possible. Usually I would recommend to perform your own transpilation if you need to run it in an unsupported environment.

Uppss, I thought react docgen was already requiring node4 at least. I go ahead and revert the breaking change for 2.x. but I would leave it for 3.x

I released v2.14.1 with @danez' changes. Let me know if that works for you!

I just tested the 2.14.1 release and it works for us. Thanks!
