QUIC: fixed using of retired connection id (ticket #2289).
RFC 9000 19.16
The sequence number specified in a RETIRE_CONNECTION_ID frame MUST NOT
refer to the Destination Connection ID field of the packet in which the
frame is contained.
Before the patch, the RETIRE_CONNECTION_ID frame was sent before switching
to the new client id. If retired client id was currently in use, this lead
to violation of the spec.
