BroadcastsData::serializeData() does not appear to process $includePaths parameter correctly.

BroadcastsData::serializeData() appears to call Encoder::serializeData(). Encoder::serializeData() does not appear to take a second parameter. And thus no matter if includes are specified or not, the data going down the broadcast wire will have no includes. Below is what BroadcastsData::serializeData() should probably look like.

// BroadcastsData.php
// ...

    protected function serializeData($data, $includePaths = null, array $fieldsets = null)
    {
        $params = new QueryParameters($includePaths ? (array) $includePaths : null, $fieldsets);

        return $this->broadcastEncoder()->withEncodingParameters($params)->serializeData($data);
    }
