Backend-layouts not properly mapped upon import
When doing an import/export of pages and backend layout records get included in the T3D file the relations to those backend-layouts will not get properly updated upon import.
Rather the fields "backend_layout" and "backend_layout_next_level" of the pages table will point to the same UID the backend layout records had on the export site.
To counteract this a "softref" field should get configured for the backend_layout fields of the pages table and a soft reference parser (or the default softref parser) should handle those fields.
