This is a regression after the merge of message containers.

See #7001.

Steps to reproduce the issue:

• start the broker from the umbrella: make run-broker PLUGINS="rabbitmq_stream rabbitmq_amqp1_0"
• run tests from the stream Java client test suite:

cd /tmp
git clone git@github.com:rabbitmq/rabbitmq-stream-java-client.git
cd rabbitmq-stream-java-client
./mvnw test -Dtest=Amqp10InteroperabilityTest -Drabbitmqctl.bin=/path/to/rabbitmq-server/sbin/rabbitmqctl
