Fixed unique ID bug in entitites

Integration

Configuration

• When trying to setup the Crownstone integration again after it has already been setup once, setup will be aborted with message "there can be only 1 Sphere in a house"

Entities

• Fixed a bug where unique ID's were not correctly generated, which caused that some power usage entities could not be created

Important!

• It is recommended to remove the integration and re-add it after updating, because new ID's are generated for all entities.
