Adjust supported Puppet version back to 4.7.1

With the New version of NodeJS v6.11.3 puppet brakes the installation on ubuntu 16.04

* Content of the node packages.
V6.11.2
```
~$ dpkg -l |grep nodejs
ii  nodejs                              6.11.2-1nodesource1~xenial1                amd64        Node.js event-based server-side javascript engine
~$ dpkg -L nodejs |grep '/usr/bin/'

```
V6.11.3
```
~# dpkg -l|grep nodejs

~# dpkg -L nodejs |grep '/usr/bin/'
/usr/bin/node
/usr/bin/npm
```

After puppet runs to install nodejs the node binary is a broken link. 
```
~# ls -ltra /usr/bin/node /usr/bin/nodejs  /etc/alternatives/nodejs
lrwxrwxrwx 1 root root 24 Sep 15 09:41 /usr/bin/nodejs -> /etc/alternatives/nodejs
