Http2Session should always call ondone into JS to detach the handle. In some case, ondone is defered to be called by the StreamListener through WriteWrap, we should be careful of this before getting rid of the StreamListener.

The test case destroys the socket governed by http2. This is not a good practice, but nodejs internal in some case does this too (e.g. when a TCP RESET is received, nodejs internal destroys the socket without bothering it is consumed by a http2 session or not) and it is the simplest code that I can come up with to produce this issue.
I stongly believe that this fixs #42710 based on the issue's description
