Pull request #126 (2018-08-27 05:05:31)

Improvements to `chai-should` codemod
* Understands more ways that `expect` can be required:
```js
const { expect } = require('chai');
```
```js
const chai = require('chai');
const expect = chai.expect;
```
```js
const chai = require('chai');
const { expect } = chai;
```
* Smarter conversion to jest expectations:
```js
expect(foo).to.equal(null);
/* --- becomes --- */
expect(foo).toBeNull();
```
```js
expect(foo).to.equal(undefined);
/* --- becomes --- */
expect(foo).toBeUndefined();
```
```js
expect(foo).to.not.equal(undefined);
/* --- becomes --- */
expect(foo).toBeDefined();
```
* Reduce data loss of chai's second expect parameter by keeping it as a leading comment:
```js
expect(foo, "Business reason why this shouldn't fail").to.equal(true);
/* --- becomes --- */
// Business reason why this shouldn't fail
expect(foo).toBe(true);
```
* Other smaller fixes including better handling of `empty` and support for `equals`, `eq` and `function`.
