tokio-quiche: Client cancels HTTP3 request

[Nadel1]

Hi!
While debugging a different issue in tokio-quiche I rebased my work and noticed that my examples aren't working anymore. Specifically, the handshake completes, but my server sends a reset request after the client cancels the HTTP3 request (as the error code in the reset_stream is 0x10c).

I've tried debugging why this happens, but haven't made any real progress and would be helpful about any help.
Steps to reproduce:

1. My used examples can be found in https://github.com/Nadel1/quiche/tree/crypto_fail/tokio-quiche/src/bin . The examples tokio-server and tokio-client are based on the example code given in https://github.com/cloudflare/quiche/blob/master/tokio-quiche/README.md
2. Set environment variable SSLKEYLOGFILE to log keys
3. Start wireshark and log loopback
4. Start server with cargo run --bin tokio-server -- --root . (I wanted to modify the README code as little as possible, so the paths to the certificate and key are hardcoded, requiring this command to be executed in the tokio-quiche folder)
5. Start client with cargo run --bin tokio-client

The client will receive the Reset event, but never the requested file. I extended the server code to deal with non-existent requested files, but that is apparently not triggered at all, since it doesnt matter whether I request correct or incorrect file paths, so it doesnt seem like the request itself is the issue.

I'd be grateful for any debugging pointers you might provide me with!
