Message footer should be handled before attempting to find the object the main message is sent to / checking permissions, because it is not aimed at a specific object. E.g. the registry generation updates should be handled regardless of whether the main message is valid or not, because the updates will not be re-sent. Fixes registry generation updates sometimes going missing.
