peer: fix bug, use the existing timestamp for the ChannelUpdate msg 

This commit fixes a lingering bug within the logic for the
peer/htlcswitch/channellink. When the link needs to fetch the latest
update to send to a sending party due to a violation of the set routing

from disk. This was incorrect as it would invalidate the signature
within the message itself. We fix this by instead
