LPS-38723 removing necessary escape methods from the edit_entry.jsp, so thatin FlagsRequestMessageListener we are not using escaped contentTitle value for notifying subscribers to the message board thread.  removed escape method from className and contentURL also for consistency.

Instead of unescaping group.getDescriptiveName in flagsrequestmessagelistener, just removed the unnecessary escape method there since the String  groupName will return the site name which should not be escaped here or it will cause the resulting vaue to display incorrectly (;amp instead of &)
