route_replies: Handle raw 482

lahwran reported the following message from *route_replies and also figured out
which message we failed to handle, thanks!

<*route_replies> This module hit a timeout which is possibly a bug.
<*route_replies> To disable this message, do "/msg *route_replies silent yes"
<*route_replies> Last request: MODE #somesecretchannel I
