HTTP/3: require mandatory uni streams before additional ones.
As per quic-http-34:
Endpoints SHOULD create the HTTP control stream as well as the
unidirectional streams required by mandatory extensions (such as the
QPACK encoder and decoder streams) first, and then create additional
streams as allowed by their peer.
Previously, client could create and destroy additional uni streams unlimited
number of times before creating mandatory streams.
