[sghuang19]

Passed tests for:

• Both package.json and package.yaml exists and has hexo in it.
• Both exist but only one has hexo in it.
• Both exist and none has hexo.
• Searching for package.json and package.yaml in dir above.

This actually shortened the code, which is quite elegant imo. 😆

Seems like I forgot to handle hexo init, will continue to fix this problem.

This change affects more moving parts than I thought. Not moving forward for now.
