Rewrite tests in TypeScript

Rewriting the tests in TypeScript should help us further identify places where TypeScript support can be improved.

Steps

1. Rename a single .test.js to .test.ts
2. Run npm test to identify errors
3. Start fixing the errors, making minimal changes to get the tests passing
4. Repeat step 2-3 until there are no more errors, or until you get stuck and want some extra eyes from someone else in the community
5. Open a pull request with your changes.

See https://github.com/probot/probot/pull/541 as an example

If I’m not mistaken, all tests have been migrated to TypeScript or have a PR open to migrate them to TypeScript. 💯
