Subject: log-forward: fix forwarding first message

Pulling the power cable results in log message on next boot:

dec/16 18:28:28 system,error,critical router rebooted without proper shutdown, probably power outage

This was not forwarded as it had the numeric id 0, which is not greater
than the zero we initialized with. Now initialized with -1 when no log
has been forwarded to fix this.
