Fix channel crash when publishing to a new stream (backport #12969)

[mergify]

The following scenario led to a channel crash:

1. Publish to a non-existing stream: perf-test -y 0 -p -e amq.default -t direct -k stream
2. Declare the stream: rabbitmqadmin declare queue name=stream queue_type=stream

There is no pid yet, so we got a function_clause with none

{function_clause,
   [{osiris_writer,write,
        [none,<0.877.0>,<<"<0.877.0>_-65ZKFz18ll5lau0phi7CsQ">>,1,
