tst_http2::earlyResponse - fix a flaky and somewhat broken test

1. Fix erroneous logic, which was triggered in 'h2' mode (non-TLS connection)
- after the initial protocol upgrade/POST request was handled, the server
(on Windows specifically) was erroneously handling upcoming DATA frames by replying
with another redirect response.
2. Make the test less heavy by sending 1 MB of Qt::Uninitialize instead of 10 MB
- theoretically this could cause a timeout before the redirected request finished
successfully.
