Fix intermittent unit test failures reseterquestor
When consumers and producers are paired as in the case of the REST Rquestor, both sides must come up and be wired together in the initiation phase of apex-pdp before the consumers and producers start handling envents. In the ApexActivator class, the consumers were started immediately after they were initialized meaning that a consumer could return events to a producer that had not started yet. This change fixes the ApexActivator so that it waits until all consumers and producers are initialized before starting event handling. It also fixes the timings on RestRequestor tests and tidies up the unit tests.
