I'm not hugely keen on this fix. While by no mean horrendous, it does convolute
the code. I think it likely that we will shortly have a modified Queue that
retains acquired messages at which point a cleaner - and more logically
consistent - fix is possible. If you do commit this, it would be good to have a
test case with it.

bq. Summary
bq. -------
bq.
bq. This patch makes one change that fixes the reported bug:
bq.
bq. Messages that are requeued from a subscription (due to closing or release)
to a deleted queue are routed through that queue's alternate exchange if one
was configured. Previously, requeued messages were placed back on the queue
regardless of whether it had been deleted.

bq. This addresses bug QPID-3481.
