Identified failing specs, commented out

I reviewed the client specs that were failing and commented out the ones that appear to be more relevant to github. Not sure if any of these might be applicable (e.g., netrc), but let me know and I'll figure out the correct data to use for it. Also, I used the dotenv gem to store the credentials you listed in travis yml file so I can test locally (creds in the .env file and added to gitignore).
