Using a prop as an object key to call a function, incorrectly reports missing in props validation

[Standard8]

Testcase:

var TestComp1 = React.createClass({
  propTypes: {
    size: React.PropTypes.string.isRequired
  },

  render: function() {
    var foo = {
      "abc": ["1", "2", "3"]
    };

    var icons = foo[this.props.size].map(function() {
      return null;
    });
    return (<div>{icons}</div>);
  }
});

Output:

  11:37  error  'size[].map' is missing in props validation  react/prop-types

✖ 1 problem (1 error, 0 warnings)

this.props.size is being used as the key for the object, not as an object itself.

Forgot to say, this is a regression in 2.6.0.

It should come from the new nested props support. I will investigate.
