Title: update chai.js to 1.4.0

The old chai's `expect` is terribly slow when expecting dom element:

```
// chai.version === "1.1.0"
console.time('n')
expect(document.body).to.equal(document.body)
console.timeEnd('n')
// => n: 932.448ms
```

versus:

```
// chai.version == "1.4.0"
console.time('n')
expect(document.body).to.equal(document.body)
console.timeEnd('n')
// => 0.141ms
```
