Improve tracking of existing entities in deconz (#40265)

* Store all entities in dict

* Use stored unique id to select if to create entity or not

* Remove unnecessary init

* Change so same physical sensor doesnt try to create multiple battery sensors
Change so groups get created properly

* Add controls in tests that entities are logged correctly
