#337)

* Excluded additional object properties from get systemsettings retrieve by fetch logic.  Longer term we may wish to consider going away from serializaing these inside the function and, instead, rely on the object returned from get-CrmRecordsByFetch

* Added null check on the name property to avoid this in the future
