Bump tesla_powerwall to 0.5.2 and accommodate optional values from the module

[nugget]

Proposed change

Bumps tesla_powerwall module, changelog: https://github.com/jrester/tesla_powerwall/compare/v0.5.1...v0.5.2

Also updates the integration to gracefully handle optional values in the module's BatteryResponse class to prevent Home Assistant from blindly attempting to perform math on possible None values associated with disabled Powerwall batteries that may be present in the system.
