Receiving Check suite web hooks, even though I've only registered for Check run

[danielcompton]

I've setup an internal GitHub App for https://github.com/chdsbd/kodiak. It asks for

* check run
* pull request
* pull request review
* pull request review comment

I've set those up in the GitHub App's settings. In the webhook logs I can also see that check_suite events are being delivered, even though I haven't registered for them. This seems like a bug?

One example event:

Request method: POST
content-type: application/json
Expect: 
User-Agent: GitHub-Hookshot/b6210f6
X-GitHub-Delivery: b2e22b80-113f-11ea-8110-55daded6fa71
X-GitHub-Event: check_suite
X-Hub-Signature: sha1=b9431e54713b46ead8b96839098ef1111f9f8d69
