Animated.Value resets if not rendered

[Elijen]

🐛 Bug Report

If render() method does not return an Animated.View that uses the Animated.Value we are animating the Animated.Value resets and will have a wrong value on the next render() call. This goes against the basic principle that render() method should be a pure function without side effects.

I suspect that this behavior also causes bugs/freezes when shouldRasterizeIOS set to true.

To Reproduce

1. Animate a Value
2. Using state show/hide the Animated.View that is using the Value periodically
3. Animated.Value will keep reseting

Expected Behavior

Animated.Value._value should not depend on the results of render() method
