FaceletViewDeclarationLanguage call StateManager.saveView() before write document

There are components that are added/removed on render response time that needs to be saved. I we call before render response, the result is this components are not saved on the tree and cause some components like t:tree not work correctly.

It seems this was changed when we move the code from facelets, but the original implementation of FaceletViewHandler shows the place where this call should be done, so I'll just restore the code as originally was.
