Doesn't find HOCs that just wrap & re-export component

Some HOCs aren't correctly parsed when they're just calling a function on an imported component. For example, exporting a HelloButton component that just exports an imported Button component wrapped in redux connect:

hello-button.js:

// @flow
import { connect } from 'react-redux';

import { sayHello } from '../actions/hello';
import Button from '../components/Button';

const mapStateToProps = () => ({
        label: 'Say something',
});

const mapDispatchToProps = dispatch => ({
        handleClick: () => {
                dispatch(sayHello('Hi!!!'));
        },
});

// HelloButton
export default connect(mapStateToProps, mapDispatchToProps)(Button);

button.js:

// @flow
import React from 'react';
import './index.css';

type Props = {
        label: string,
        handleClick: Function
};

const Button = ({ label, handleClick }: Props) =>
        <button styleName='button' onClick={handleClick}>{label}</button>
;

export default Button;

Button is properly parsed, but HelloButton is not considered a component, even when using the findAllComponentDefinitions resolver.

Start with the hello-button.js and button.js examples, then trace the findAllComponentDefinitions resolver to see why a component imported and wrapped by connect is missed. Confirm the change by checking that HelloButton is recognized as a component while Button remains correctly parsed.
