v5.0.4+ - Exceptions not propagating to ChildResults

[ntieszen]

Kind of along the similar track as another recent issue #653

Something changed between version v5.0.3 and 5.0.4 where a Rule Expression exception is no longer assigned to the ChildResults ExceptionMessage property. Can you please look into this?
