Proposed change

_async_update_attrs isnt being run at start up for Wall Connectors, which is causing entities to have an initial unknown value. This gets fixed after the first refresh, but this PR makes it correct from the start (including the snapshot)

Suitable for a point release, but not urgent since its fixes itself after first refresh.
