Run unsubscribe callbacks when Assist satellite entity is removed from HA

[synesthesiam]

Breaking change

Proposed change

Renaming the entity id of the Assist satellite causes it to subscribe twice to voice assistant events, requiring the config entry to be reloaded for voice functionality to work.

Rather than unsubscribing on disconnect, this PR runs the unsubscribe callbacks in async_will_remove_from_hass
