Crash for projects with locale subfolders without a .yml file

[oliverklee]

https://github.com/braingourmets/gethdo/releases/tag/test%2Fyaml-lint

In this project, we have nested subfolders for the locales. Particularly, we currently have EN and DE locale files directly in the config/locales/ folder, and then some files in config/locales/views/home/index. Running yaml-validator on this causes a crash:

I think it's happening because the en.yml file is empty (it just has the header),
so the root yaml_object is a string and not an object.
