Before this change, eqmx_mock_client uses a shared ets table to store last received message, this causes troulbe when we want to start / stop two or more clients in one test case the ets table gets owned by the first spanwed client and gets closed when the owner client dies. Now it keeps the last received message in process state and a gen_server call is added to retrieve it for verification Along with this change in emqx_mock_client, it made possible to write test case to verify the actual subscriber pid used in shared subscription strategy, so test cases were added (and modified) to verify different strategies
