Use proper night time icon consistently for sun integration

[spacegaier]

Breaking change

Proposed change

Ensure that for the "sun" integration the state badge, glances and more-info consistently show the same icon. It is now based upon the above_horizon and below_horizon state.

The icon I used for night is also used e.g. by the alarm integration for night arming.
