breacharbiter: fix double channel close panic bug

Browse Source 
This commit fixes s bug in the breachArbiter which was introduced
during the change that added the live channel hand off from an active
peer. Rather than closing the settle channel of the _older_
breachObserver, the settle channel of the newer beachObserver was being
closed. This would result in a panic once the channel itself was
actually settled as the channel would be closed again.

To fix this bug, we now properly close the channel of the old settle
signal instead of the new one.
