[inspector] use creation stack trace as parent for async call chains

Creation stack trace points to the place where callback was actually chained, scheduled points where parent promise was resolved.
For async tasks without creation stack (e.g. setTimeout) we continue to use scheduled as creation since usually they are the same.
