Fix _serialize and Paginator

Now let's do some fixes to the _serialize and paginator on cells:

• Since setting view var _serialize is deprecated, use ViewBuilder::setOption('serialize', $value) instead.
• Use $this->request->withAttribute instead $this->request->withParam
• Use $this->request->getAttribute instead $this->request->getParam

See this to get more information about paginating data inside a cell
