> [AMQP] sender is not granted credit once space on queue is available

> Attachments: drain.py, test_send.py

>
> If an AMQP publisher sends to a queue that is full, with
> address-full-policy=FAIL, it gets messages rejected and no credit issued as
> expected. However if the queue is then drained, that existing sender link is
> not granted any more credit.
> To reproduce, configure a broker such that it has a queue called examples
> with some fairly low max size (I set global-max-size to 100kb) and
> address-full-policy of FAIL. Then run attached test_send.py with args e.g. -m
> 100000. The sender will eventually stall due to lack of credit. Then run the
> attached drain.py which will drain the queue. This *should* allow the sender
> to resume sending, but it does not.
