fix(node/http): don't throw on .address() before .listen() (#24432)

It's perfectly valid to access `server.address()` before calling
`.listen()`. Until a server actively listens on a socket Node will
return `null` here, but we threw a "Cannot access property 'port' of
undefined" instead.

This was discovered when inspecting failures in Koa's test suite with
Deno.
