This fix the invoice create form when we provide `origin` element in
url. The actual create form overide the value for origin field with
`$objectsrc->element`. This make creation of invoice originating from a custom
module module impossible because we need the module part to instantiate
the class for the custom module object.
This also modify Common Object::fetch Object Linked() to append the
module part for `$sourcetype` and `$targettype` if it not set and object
have module property and it not in core module.
