Fixed method prunePendingRequestQueue() which removed all requests except processed.

Method prunePendingRequestQueue() remove all pending requests except processed because method getNextPendingRequests(0) always return empty array.

Just another solution.

Добавил в composer.json
"require": {
"chuyskywalker/rolling-curl": "*"
}

Сделал composer update, выкачивается старая версия:

public function prunePendingRequestQueue()
{
    $this->pendingRequests = $this->getNextPendingRequests(0);
    $this->pendingRequestsPosition = 0;
    return $this;
}
