HAP-Python 3.4.0 breaks bridge with multiple accessories
I have a bridge that consists of two accessories:

- Temperature & humidity sensor
- Motion sensor

Everything was working okay with HAP-Python 3.3.0, the behavior described in ikalchev/HAP-python#327 notwithstanding.

However, after upgrading to HAP-Python 3.4.0, my motion sensor stopped working.  I have an `run()` method defined for each accessory, like below, where it outputs something to the log each time the method is invoked.

```python
@Accessory.run_at_interval(5)
async def run(self): ...
```

My `get_bridge()` method looks like this:

```python
def get_bridge(driver):

    '''
    Call this method to get a Bridge instead of a standalone accessory.
    '''

    bridge = Bridge(driver, 'Study HAP-Python Bridge')
    bridge.set_info_service( ... )

    temp_humid_sensor = TemperatureAndHumiditySensor(driver, 'Temperature & Humidity Sensor')
    bridge.add_accessory(temp_humid_sensor)

    motion_sensor = MotionSensor(driver, 'Motion Sensor')
    bridge.add_accessory(motion_sensor)

    return bridge
```

So I should see some log entry from each accessory every 5 seconds or so when `run()` is invoked.  But with the code as-is, I only see my output from the `temp_humid_sensor` accessory.  I still see `DEBUG` log chatter talking about the motion sensor, but nothing from log entry orchestrated in its `run()` method.

If I comment out the two lines with the `temp_humid_sensor` and restart the service, then I will see the output from my motion sensor accessory.

Also, if I uncomment the two lines and downgrade to HAP-Python 3.3.0, then I once again see output from both accessories every 5 seconds.

I will stick with HAP-Python 3.3.0 for now.
