Only one device available

When trying to run to a second device using a different MAC address the turn on script fails. The scanner seems to see all the available devices, but only connects to one.

Connecting to: 58:93:D8:3E:D2:DB Disconnected from: 58:93:D8:3E:D2:DB Failed to connect to: 58:93:D8:3E:D2:DB Traceback (most recent call last): File "/home/ian/Downloads/melnor-bluetooth/turnon1.py", line 17, in <module> asyncio.run(main()) File "/home/ian/anaconda3/lib/python3.9/asyncio/runners.py", line 44, in run return loop.run_until_complete(main) File "/home/ian/anaconda3/lib/python3.9/asyncio/base_events.py", line 647, in run_until_complete return future.result() File "/home/ian/Downloads/melnor-bluetooth/turnon1.py", line 12, in main device.zone2.is_watering = True; File "/home/ian/Downloads/melnor-bluetooth/melnor_bluetooth/device.py", line 304, in zone2 if self._valve_count > 1: AttributeError: 'Device' object has no attribute '_valve_count'

This admittedly isn't a well defined case. The primary consumer for this lib is Home Assistant and the state machine there handles separate instances of Device for me.

I'll be refactoring this library quite a bit to better support some new bluetooth best-practices in Home Assistant. That work will likely significantly change the outer loop for handling devices.
