BHV-12785 : propagate parameter to doAnimateFinish()

## Issue 
Slider: Undefined (NAN) Value displays via 5way

## Cause
Currently, SliderSample are using onAnimateFinish event for updating their status
But, after the change (ENYO-11 Updating documentation), onAnimationFinish doesn't include 'value' on it.

## Fix
propagate parameter to doAnimateFinish
