This will ensure that we don't leak any memory while playing back audio. There is an expectation value in the test that is only set to true when PulseAudio is present for the moment. When any new implementation is added for other libraries/platforms, we should hopefully get a CI failure due to unexpected success in creating the `PlaybackStream`. To ensure that we clean up our PulseAudio connection whenever audio output is not needed, add `PulseAudioContext::weak_instance()` to allow us to check whether an instance exists without creating one.
