TypeError: vantage._pause is not a function

After I've fixed the #67 error when I connect to a server via vantage client, I get an error printed to the client console :

(node:19581) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): TypeError: vantage._pause is not a function

I've not found the actual code that causes this error.

Vantage version: 1.7.0 Node: 6.8.0

After further investigation I've found out that this error is triggered HERE. The vantage variable refers to the Vorpal object which does not have the _pause property at all.

I can't get even a simple vantage remote server connect working.
