Error event judgement in file 'stream.js'

[j78742]

// according to baygeldin/ws-streamify#1
// Nodejs WebSocketServer cause memory leak
// Handlers like onerror, onclose, onmessage and onopen are accessible via setter/getter
// And setter first of all fires removeAllListeners, that doesnt make inner array of clients on

var eventListenerSupport = ('undefined' === typeof socket.addEventListener)

The sign ‘===’ in this line of code should change to ‘!==’.
