Config_flow updates, fix notification
Plugwise-beta changes:
- Same config_flow unique_id when configuring via zeroconf discovery or via manual entry (zeroconf not used in beta), fixes home-assistant/core#38389
- Fix config_flow "unique_id = None" for Smile P1 v2 (home-assistant/core#38388)
- Use
async_update_entry()to make sure the two above changes do not break something - Binary_sensor code improvements
- Fix notifications not automatically clearing (introduced in HA Core 0.113?), fixes #98.
