dangerouslySetInnerHTML and text() not outputting

I have a simple `

` component that has a `dangerouslySetInnerHTML` and when doing a shallow render of:

```

`_wrapper.find('p').text()` doesn't return 'blah' as expected.
`_wrapper.find('p').html()` returns 'blah' wrapped in the `

` tag.

Have a [branch](https://github.com/silasb/enzyme/tree/dangerouslySetInnerHTML-node-text-func-error) that proves that `text()` doesn't work

Start with the dangerouslySetInnerHTML-node-text-func-error branch and reproduce the shallow render using find('p').text() and find('p').html(). Compare the two traversal results and confirm that text() returns 'blah' while html() returns the content wrapped in the p tag.
