Destructuring a value off of a stateless function causes false prop-types error

[kentcdodds]

As noted in #735:

Here's how I can reproduce the issue:

import React, {PropTypes} from 'react'

function Foo({bar}) { // react/prop-types error reported for bar on this line
  const {baz} = Foo
  return <div>{baz} {bar}</div>
}

Foo.propTypes = {
  bar: PropTypes.string.isRequired,
}

Foo.baz = 'hi'

This does not produce any error:

import React, {PropTypes} from 'react'

function Foo({bar}) {
  const baz = Foo.baz
  return <div>{baz} {bar}</div>
}

Foo.propTypes = {
  bar: PropTypes.string.isRequired,
}

Foo.baz = 'hi'

Here's a real use case

Looks like destructuring a property off of the function (whether inside the function itself or not) is causing issues.
