cells: Fix local delivery to queues

Motivation:

Cells may consume messages from named queues. When they do, a
queue route is installed that routes messages sent to the queue
to the consuming cell.

This fails because the routing logic delivers the message as
if to a tunnel. Thus the message isn't corrcectly decoded before
delivery to the cell, resulting in a null pointer exception.

This was not discovered earlier as delivery will succeed if the
cell has the same name as the queue - in that case delivery is
directly to the cell rather than through the queue route.

Modification:

Add the same kind of destination address rewriting logic already
used for alias and topic routes. This causes the message to
delivered as a message event rather than a routing event.

Result:

Fixed a bug in which delivery of messages to cells would fail
if the cell name was different from the cell service name.
