at this point we're not really calling getPublicInstance at all. These lines could change to return component._instance perhaps (relevant commits: d395726, eg)
I'm wary of changing what appears to be the sole purpose of this method (to have different logic for SFCs). Could we change where findDOMnode is called instead? I'm not sure what would be best.

All of the methods that call findDOMNode are wrapped in single calls which pass in this.node which is returned by getWrappedComponent so this seems like the most logical place to make the change.
Unless there's another method to get the instance for SFCs specifically none of the methods dependant on findDOMNode will work (html, text, simulate)

Thinking about it more, it seems like React doesn't want you to be able to call findDOMNode on SFCs so the alternative might just be documenting that those methods don't work on SFCs.

Alternatively/additionally, throwing a more helpful error here

Resolves #356
getPublicInstancereturnsnullfor SFCs and the_renderedComponentappears to be a wrapper component that doesn't actually have arendermethod. This causesfindDOMNodeto fail as it uses therendermethod to validate that an object is a React component.This returns the internal
_instanceinstead of returningcomponentwheninst === null.I was thinking of maybe doing
return component._instance || componentto be extra safe but it didn't seem to make a difference.
