INT-3448: Addressing PR comments
Late Resolution of @Publisher.defaultChannel
Early resolution of the publisher default channel caused
`@ Configuration` factory beans to be instantiated before
Spring Integration bean post processors had been registered.
Use the channel name instead of channel reference and resolve
it when processing the first publish.
