core: scene.create snapshot_entities does not respect colour temperature for mqtt lights

A script runs stuff and is supposed to restore the state. Applied to a Zigbee light group.

library_flash:
  alias: "Library: flash"
  mode: single
  sequence:
    - service: scene.create
      data:
        scene_id: before
        snapshot_entities:
          - light.library
    - repeat:
        count: 3
        sequence:
...
    - service: scene.turn_on
      data:
        entity_id: scene.before
        transition: 5

Restores brightness, but not colour temperature. The same script restored all fine when the light was controlled by Hue Bridge. Manual control of the light group, as well as the light bulb directly, works well, with all properties respected.

Environment

HA 2021.1.1. Zigbee2MQTT, Mosquito 2.0.4. Hue White Ambience E27 light.

Problem-relevant `configuration.yaml`

...
light:
  - platform: mqtt
    schema: json
    name: Library
    command_topic: "zigbee/lights_library/set"
    state_topic: "zigbee/lights_library"
    color_temp: true
    brightness: true
    rgb: true

@kevincaradant #45522 makes it possible for zigbee2mqtt to make the color mode of the light clear when it reports the state. However, zigbee2mqtt also needs to be updated.

@Koenkk Please have a look at the changes in #45522, this will allow setting the light’s color mode to white or color by setting color or color_temperature to null in the state update map.

Please note that it’s not intended to try to translate the color_temperature to a color, Home Assistant expects the light be be either in color or in white mode, although this is not currently enforced when updating the entity’s state.

@kevincaradant Thanks for the log! The reason it doesn’t work is precisely that both (a not exactly valid) xy-color and a color temperature is stored in the scene. When the states are restored, only the xy-color is sent to the light.
