Describe the bug

#14229 has introduced a regression in 4.1.3:

GET /api/deprecated-features/used returns an empty state field/

Reproduction steps

1. Declare a transient classic queue
2. curl -s -u guest:guest -X GET http://localhost:15672/api/deprecated-features/used | jq
3. Inspect the response

Expected behavior

Either the state field should be set correctly or skipped.

For comparison, here is the 4.1.2 output:

[ { "name": "transient_nonexcl_queues", "desc": "", "deprecation_phase": "permitted_by_default", "doc_url": "https://blog.rabbitmq.com/posts/2021/08/4.0-deprecation-announcements/#removal-of-transient-non-exclusive-queues", "provided_by": "rabbit" } ]
