Support ES5

[chrisprobably]

Describe the feature you'd like:

I'd like react-testing-library to build an ES5 compatible build. At the moment, I can see there are arrow functions in dist/index.js of version 5.4.4.

Suggested implementation:

Suggest the same fix as testing-library/dom-testing-library#160

Hmmm... Where are you running your tests?

[kentcdodds]

I'm going to do the same fix as in dom-testing-library, but I'm just curious what environment you're running your tests in that doesn't support arrow functions.

[chrisprobably]

Great, thanks :). We're using karma, webpack and Babel. We don't normally transpile dependencies in node_modules.

[kentcdodds]

Gotcha. So I take it that you're running some of your tests in IE then?

[chrisprobably]

Yes, we run them in IE11.
