Use Scene result for SingleUserScene (#6909)

* Scenes should return resulting data in the result object

The result is for data that cannot be known by the client requesting the scene and the mangle map used for mangling input values to enable parallelizing tests

* Fix filenames

* SingleUserScene now has a return value of various created User data

* 1/100 too frequent for false test failures
