enable eslint for test files (#1363)

We've had a few issues where .only in tests wasn't getting caught by our
lint rules. Turns out it's because we were excluding tests from eslint
completely

### Change Type
- [x] `internal` — Any other changes that don't affect the published
package (will not publish a new version)
