Notifiee.ListenClose is never called

[vishalchangraniaxiom-old]

Hi,
I have implemented a notifee and passed it to the basic host by my connection manager.
All the interface methods except this one Notifiee.ListenClose get callbacks. Upon investigation, I found that in the Go Libp2p source there are no callers for the ListenClose method. Will a call be added anytime soon?
I have several tests which start and stop several libp2p nodes and they fail intermittently. I suspect the ports are not closed fully before the next test start and that may cause a new libp2p node connecting to an old one which is being brought down. ListenClose would have helped me resolve that with a done() channel.

It probably won't. Libp2p does wait for all listeners/connections to stop before returning from Close. However, we should still fix this.
