Title: Cleanup FeedbackSubmissionEditPageAction #1863

FeedbackSubmissionEditPageAction

+ Add test case closed session
+ Remove unnecessary conditional to check for null and throw exception since it will already be thrown by getDataBundle function.
+ Refactor some confusing code
+ Remove unused variable

Also cleans up FeedbackSubmissionEditSaveAction (no issue created.)
