V2Writeable.pm: Ensure that a found message number is in the msgmap

The lookup to see if a num has already been assigned to a message
happens in a temporary copy of message map.  It is possible that the
number has been removed from the current message map.  The
unindex/reindex after a history rewrite triggered by a purge should be
one such case.  Therefore add the number to the msgmap in case it is
not currently present.
