Entity<TResource>.UpdateAsync now checks for HttpStatusCode.NoContent
H6. Resolved
* DVPL-4891: Entity.Update method should return true or false based on what is found in the response body.
H6. Test changes
* Removed SdkHelper.GetOrElse
* All tests use MockContext.GetOrElse, not SdkHelper.GetOrElse
