Add sorting in order.

[rodoabad]

I' like order to have the same the member sort rule that sort-imports have.

import {hashHistory} from 'react-router';
import {syncHistoryWithStore} from 'react-router-redux';

VS

import {syncHistoryWithStore} from 'react-router-redux';
import {hashHistory} from 'react-router'; // error
