fix: 兼容 1.0 class 组件在 Web 下 transitionEnd 回调失效

[balloonzzq]

import findDOMNode from 'rax-find-dom-node';
import { createElement, Component, render } from 'rax';
import Text from 'rax-text';
import transition from 'universal-transition';

export default class App extends Component {

  constructor(props) {
    super(props);
    this.textRef = null;
  }

  componentDidMount() {
    const ref = this.textRef;

    transition(findDOMNode(ref), {
      opacity: '0.5'
    }, {
      duration: 1500
    }, () => {
      console.log('transition end');
    });
  }

  render() {
    return <Text ref={ref => this.textRef = ref}>test</Text>;
  }

}

在 web 下，该示例可复现 callback 失效。

还要再看看为什么需要 setTimeout，以及顺手迁移一下 build-scripts 吧
