Title: =per #3933 Correction of seq number logic for persistent channel

* Problem when using PersistentChannel from Processor
* When the seq numbers of the sending processor and the seq numbers
of the PersistentChannel was out of sync the PersistentChannel
did not de-duplicate confirmed deliveres that were resent by
the processor.
* There is a hand-off in the RequestWriter that confirms the
Processor seq number, and therefore the seq number of the
RequestWriter must be used in the ConfirmablePersistent from
the RequestReader
* More tests, covering this scenario
