http2: fix regression on upload EOF handling

- a regression introduced by c9ec85121110d7cbbbed2990024222c8f5b8afe5
  where optimization of small POST bodies leads to a new code path
  for such uploads that did not trigger the "done sending" event
- add triggering this event for early "upload_done" situations

Fixes #11485
Closes #11487
