Support for Node 10

[Dachi Natsvlishvili]

I have changed

- name: Ensure Node.js and npm are installed.
  yum: "name=nodejs-{{ nodejs_version[0] }}.* state=present enablerepo='epel,nodesource'"

this to

- name: Ensure Node.js and npm are installed.
  yum: "name=nodejs-{{ nodejs_version.split('.')[0] }}.* state=present enablerepo='epel,nodesource'"

or it was picking '1' from '10.x'

I can confirm the same issue with Node 10.x

This was fixed via #80. Thanks for reporting!
