Correct initial playback time in some sendMetaData() calls in tests
When BUFFERING completes, ignored a deferred seek operation if the target time is near the current time. This avoids a situation where we attempt to JumpForward()/JumpBackward() and the device reports success but ignores the request, leaving us in the BUFFERING state.
Add tests for deferred seeking to near (before) and near (after) the current time
