Reanimated 1.3.0 Node values are updated when they shouldn't

Hello there.

As I mentioned in #415, after 1.3.0 upgrade my animation node values are updated even when another node value (in different component) is changed (and no state change is made). Whats worse, even when I push a new screen and then go back, origins screen nodes values are changed. But all these problems disappears when I remove diffClamp method.

It happens only on 1.3.0. When I downgraded back to 1.2.0 the issue dissapears.

I’m enclosing reproducible demo https://github.com/sebinq/react-native-reanimated-bug

Steps to reproduce:

1. At HomeScreen, move any object just a little bit to any side.
2. Change Screen using provided button.
3. Go back to HomeScreen and you will see position is changed!

You can also see debug log in console that translation value was changed.

When you remove diffClamp in ‘components/Movable.js’ and try to use just withOffset, you can see that everything works fine!

Thank you so much for any help!
