ValuesRangSlider generates 2 events when changed. Same issue for HS3 or HS4 plugin

[dcorsus]

I'll generate an issue on GitHub for HS4 but wanted to post it here for urgency wrt running HS3 PIs unmodified under HS4 when HS4 is soon launched.

the PI receives 2 back to back events when I adjust the range slider in the devices view. First with correct new value followed immediately by an event with new value = 0

I have the same issue with the light, I receive the value (ex: 50) then I receive a 0, So the light stay off.
