Title: NPE in createFeedbackResponse #2675

For Issue #2675

When creating the feedback response, if entity already exists, the code will update the feedback response instead. However, the current code does not do quite a number of null checking, so replacing it with the actual updateFeedbackResponse method should solve the problem.
