Relax inspector_websocket.DispatchNotificationsUntilDone timeout condition

Modify inspector_websocket.DispatchNotificationsUntilDone to only timeout since
the last byte received.
This patch also clean up the MockTimer API a little bit by making sure that
the module's time package is replaced when mock timer is gc'ed.
