test: do not race server.close with timeout
Refs: https://github.com/nodejs/node/issues/43680
This fails when server.close()
manages to close the connection before the timeout has fired.
Here is the original issue: https://github.com/nodejs/node/issues/33734
It is not about the behaviour when racing server.close()
with the timeout - it is about the timeout not firing at all. I am removing the race condition as I don't think there should be any guarantees on which callback should fire first.
