TrackTintColor not updated when value updated outside of component.

[CorentinClabaut]

When the value is updated outside of the component, the thumb are updated correctly, but the max/minTrackTintColor is not updated.

That is the case with an array of 2 values. I didn't try with another number of values.

I can check that issue doesn't occurs in web version. Only android and iOS.

@andremawad I opened #421 with your patch (it works for me)
