test(aerospike): close agent between config suites

The Aerospike spec loaded a fresh mock agent for the default and custom-service suites but only closed one listener after the whole version block. The next load could inherit overlapping tracer URL state and drop the second version's command spans.\n\nPair each agent.load with its own close, and use the tracer returned by that load for peer-service and naming-schema helpers.
