Adding ability to clear list of sent VirtualSensorEvents from ShadowV…

…irtualSensor

Within a single test suite, if you send VirtualSensorEvents to a ShadowVirtualSensor in testA then call ShadowVirtualSensor.getSentEvents() in testB, then you will see stale data leak from the last test. This new method will help clear stale stale between tests.
