What OS are you using?

Windows 10

What version of Dramatiq are you using?

1.14.2

What did you do?

Using the RabbitmqBroker, publish a message actor.send(...) then call broker.close() more than 1 time. Looking at the code, it might not be required to publish a message.

What did you expect would happen?

A broker can be closed many times without side effect.

What happened?

One of the step of the close() method is to silence some noisy loggers. After leaving my application running for a while, I noticed that the same log filter is added multiple times.
