Cannot import extend-expect as per README.

[antsmartian]

Hello @kentcdodds ,

In the README, we have specified that we could use the extend assertions by importing:

import 'react-testing-library/extend-expect'

infact this throws an error:

  Cannot find module 'react-testing-library/extend-expect' from 'HelpTest.js'

only the below works:

import 'react-testing-library/dist/extend-expect'

Will debug this and let you know whats happening here.

We forgot to add the file to the package.json files list.

@kentcdodds Exactly, will raise a PR in sometime.
