onFirstPage() and hasMorePages() not working as intended

[janboddez]

Since next and previous URLs are always provided, I don't think the following methods work as intended:

    public function hasMorePages()
    {
        return $this->meta['next'] != null;
    }

    public function onFirstPage()
    {
        return empty($this->meta['previous']);
    }

These might:

    public function hasMorePages()
    {
        return $this->meta['has_next'];
    }

    public function onFirstPage()
    {
        return ! $this->meta['has_previous'];
    }
