fix: attaching observer in kopytkoRoot

[RadoslawZambrowski]

What did you implement:

initKopytkoRoot function attaches observers for dynamic props before calling initKopytko, thus it is possible that field change callback kopytkoRoot_dynamicPropChanged is called before initialization is completed. And this is because initKopytko updates the component with provided dynamic props by calling m.top.update(dynamicProps)

How did you implement it:

Moved attaching observers after the initKopytko call

How can we verify it:
