display-name false negative with React.createClass and ES6-style method

[peet]

I initially raised #650 because I had many components not reporting display-name issues when being assigned directly to module.exports (and ending up with 'exports' as the name in the devtools).

I've since done some for investivation and narrowed it down to using React.createClass() passing in an object containing an ES6-style method.

This does not report an error for "react/display-name": "error"

var React = require('react');
module.exports = React.createClass({
  render() {
    return null;
  }
});

or even:

var React = require('react');
module.exports = React.createClass({
  method() {},
  render: function() {
    return null;
  }
});

Further, it has something to do with the method() property having its own 'name', not the whole class, as this also does not trigger the display-name error:

var React = require('react');
module.exports = React.createClass({
  method: function method() {},
  render: function() {
    return null;
  }
});

and

var React = require('react');
module.exports = React.createClass({
  render: function named() {
    return null;
  }
});
