spring2maz 3b9247994d Refine emqx_mock_client
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
