protocol-native: footer pre_demarshal must come first

Browse source 
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.
