"Follow -> QUIC Stream" functionality doesn't work

Summary

"Follow -> QUIC Stream" functionality doesn't work right now. It always displays stream 0

Steps to reproduce

Open any QUIC traces (with decryption keys), select a packet with a QUIC stream, and right click on "Follow -> QUIC Stream" menu. You should see the "proper" stream flow; instead you always see the stream 0

Relevant logs and/or screenshots

Looking at the code, it is quite clear that this functionality is still a work-in-progress

        // XXX Look up stream ID for the current packet.
        guint stream_id = 0;
        *stream = conn->number;
        *sub_stream = stream_id;
