The upgrader test that checks if disconnect and connect events are being emitted fails intermittently as well as https://github.com/libp2p/js-libp2p/actions/runs/5117265449/jobs/9200220113?pr=1779 as result of a stream reset which seems to be related to the identify tests not closing streams.

It also results in our node tests occasionally hanging which eventually get shutdown by Github's CI.

As @achingbrain mentioned perhaps we could instrument the setup of the tests with why is node running so that we could have a log dump when CI kills prolonged running tests. This isn't ideal as the logs will still be quite noisy but it can be a start.

       should emit connect and disconnect events:
     stream reset

Yamux is selected as a muxer, but then the interesting thing here is that it fails to negotiate identify and circuit relay/stop over the connection. Yamux then closes the connection which I would imagine is what causes the reset.

So there may be a race condition on startup - are connections being opened before the protocol handlers are registered?
