Update Hyperclient object creation

Hey guys!

I was using this on a project and saw that hyperclient has changed so much in the past few months that has even changed its connection API. This pull updates william-client in order to correctly create the Hyperclient object. 

Sounds nice, right? Well, what can I say... Sometimes life is a mess, and somethings have a hidden side. A downside. The hidden face of the moon. The other side of the coin. Some of these times you find yourself in an awkward situation that you don't know how to solve. It's just too embarassing. This pull request is one of those situations: there's a broken test that I don't know how to fix :(

Anyone cares to help? :) Thanks bros!
