Client crashes if app adds any functions to Array.prototype (or Object.prototype)

[yankov]

Code to reproduce

Array.prototype.include = function(value) {};

var kafka = require('kafka')

new kafka.Consumer().connect().subscribeTopic('juggernaut')
console.log("Consumed message:", message)
})

Throws

TypeError: Cannot read property 'length' of undefined

It looks like when iterating topics it gets functions from Array for some reason and then tries to threat them as real topics.
