Stop error messages being misleadingly generated when on client connection activity timeout, a root connection triggers a CloseAgent to a neighbour region which has already closed the agent due to inactivity.
Stop error messages being misleadingly generated when on client connection activity timeout, a root connection triggers a CloseAgent to a neighbour region which has already closed the agent due to inactivity.

Also separates out log messages to distinguish between close not finding an agent and wrong auth token, and downgrades former to debug and latter to warn
