prop-types doesn't check nextProps of componentWillReceiveProps

[Eschon]

This is kind of related to #801 but as far as I can tell the PR to fix (#792) it doesn't fix my issue. I modified the reproduction case from #801 there to show my issue:

import React, {PropTypes} from "react";

export default React.createClass({

  propTypes: {
    bar: PropTypes.func,
  },

  componentWillReceiveProps (nextProps) {
    if (nextProps.foo) { // this line should trigger the 'prop-types' rule but doesn't
      return;
    }
  },

  render () {
    this.props.bar;
    return <div />;
  }
});

@yannickcr seems like it isn't fixed:
react/prop-types doesn't warn if I get props from nextProps

In this case there should be an Error about x as well.

@Eschon did you resolve the issue?

Since this is from a year ago, could you file a new issue for your use case?

Yes, today I'll do it
