RuntimeWarning: coroutine '_ContextManagerMixin.__aexit__' was never awaited

[rad-pat]

Since upgrading to latest aiormq, we see a number of these warnings in the logs. I enabled tracemalloc in our CI environment to reveal this Traceback. Hope it is useful to identify an issue?

RuntimeWarning: coroutine '_ContextManagerMixin.__aexit__' was never awaited

Potentially also useful, I see a Traceback from the early morning in the CI environment where very little is happening overnight, just a daemon task checking in which is publishing a message in RMQ. Somehow an asyncio.TimeoutError has occurred generating a Traceback that looks related to the same code:

Traceback (most recent call last):
  File "/usr/local/lib/python3.11/site-packages/aiormq/abc.py", line 40, in __inner
    return await self.task
           ^^^^^^^^^^^^^^^
asyncio.exceptions.CancelledError

The above exception was the direct cause of the following exception:
