requestChannel fails to register new data channel initiated from peer

[jtj02]

The callback from requestChannel is never called when the following code is run at either end of a call. The channel:opened callback is never run on the slave side either.

qc.on('call:started', function(peerId) {
   if (qc.isMaster(peerId)) {
        qc.createDataChannel(newChannel);
    } else {
        qc.requestChannel(peerId, newChannel, function() {
            console.log('requestChannel callback fired');
        });
    }
}

qc.on('channel:opened', function(id, dc) {
    console.log('channel opened');
});
