Merge pull request #114 from mntnr/gh-actions

ci(workflows): added GH Actions and removed TravisCI/Greenkeeper

3.8.3

fix: rate limit detection (#108)

`body` is not null. In my experience I got:

```json
body: '{"data":{"rateLimit":{"cost":1,"remaining":0,"resetAt":"2019-08-05T12:01:30Z"},"node":{"comments":{"pageInfo":{"endCursor"...
```

I'm not certain why it would need to be `null` and why inspection of the header wouldn't suffice.

`statusCode` check is also unnecessary, `queryRequest` rejects for non-200 responses so `rateLimited` will not be called in this case.
