test: Fix flaky test_request_queue_collection_iterate

Drop the limit=10 cap so the iterator walks all of the user's queues;
under the parallel integration suite, other tests creating queues
concurrently could push the just-created ones past the 10-newest
window and the inclusion assertion would fail.
