[FIX] fix debug mode: correct id and xml_id (web client)

This commit fixes two issues with debug mode:
* when a default searchview is requested, it is
initialized without its view_id. Problem is that it prevents debug mode from editing the view.
*  add xml_id in Edit action form view(debug mode) : this makes the xml id visible in form view
