Improve naming of Hue entertainment area sensors

[marcelveldt]

Proposed change

Entertainment areas show up as sensors on the Hue Bridge device to tell you if
they are streaming. Those sensors were named after the area only, for example
"Bedroom", which gives no clue about what the sensor actually is. It gets even
more confusing when the entertainment area has the same name as a room or zone.

• Entertainment area sensors are now named "Entertainment area "
• That name is now translatable
• Existing entity IDs stay the same, only the displayed name changes
• Added tests for the entertainment area sensor
