The mesh deletes a module's kept data only through drop and recreate (ADR
0595 §4 as its insight has it; design 25 § 12.3): nats_stream_remove,
nats_bucket_remove and nats_consumer_remove read the keeper's own state asked
and refuse a stream or bucket the keeper made, before the bus is reached,
naming nats_drop and nats_recreate; one that cannot be told apart is not
removed. The old sections' entries are removed as before. Rows of the
existing refusal test.
