Move completeUpgrade to WebSocketServer.prototype

[lpinca]

This brings the following changes:

• Merge the upgrade function into WebSocketServer.prototype.handleUpgrade().
• Extract completeUpgrade from upgrade and add it to WebSocketServer.prototype.

It's coveralls which is drunk, tests pass :)

@lpinca Yeah, I guess it complains when coverage gets reduced somehow.

kinda weird as coverage is exactly the same.

[3rd-Eden]

Well, the statements, branches and lines have less coverage in this branch.

[3rd-Eden]

But what ever, it's not that important.

[lpinca]

If you compare it with the total statements it's the same.
I mean, there are 3 less statements now so those 3 statements previously covered are no longer covered.
Percentage is indeed lower.
