Delay automatically closing the stream with setImmediate in order to allow any pushStreams to be sent first. Also disable the readable side of the pushStream since there should never be any data incoming.

I'm not able to make a test since technically what we were doing was fine (and works with our own client) but the browsers seem a bit too strict.

Fixes: #20992

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes

@jasnell I remember we discussed this, and you had a very good reason why this was there. Can you please weight in?

I tested this extensively and I couldn't see a good reason. We (or nghttp2) don't let through any data from the other side as is anyway, so making the readable side open doesn't seem to make much sense... Would definitely love to know if there's something I missed though.

If I am recalling correctly, this was there because of an earlier iteration. I don't think this is necessary now.

ping @jasnell — would appreciate your review, in particular whether we're safe to set readable to false and if not, why not. Thanks!
