Ensure npm/yarn installable

[zelima]

A lot of people will install the CLI tool using package managers such as npm/yarn. To provide them a nice experience we want to double check if everything works.

Notice, package name was changed recently, now it's called data-cli - check docs, blog posts and any other writings and update instructions.

I know you created a Travis task to test sudo npm i -g data-cli, how is it going on? Could we close this issue?

Please paste link to Travis build here

@AcckiyGerman @zelima the Travis is now running in the data-cli repo: https://travis-ci.org/datahq/data-cli

FIXED:
Install npm/yarn tests runs in the Travis for every push.
