RGBW2 sliders go to 0 when “all off” is used

[Didiervu91]

When using the flowcard “turn off all lights” the dim level sliders of both RGB and white channel go to 0%.
Resulting in always having to set the dim levels again when turning on the device.

This only happens when using this specific Homey flow card. In all other cases when turning off the light/device (for example just using the on/off capability) it just turns it off while keeping the values of the dim levels like it should.
