Add scenario hook errors to first and last steps

[vearutop]

Description

This PR fixes contextualized hooks introduced in #409 in the way how errors are handled.

Motivation & context

Original implementation of new hooks did not provide enough visibility to errors emitted by scenario hooks.
Test run would fail silently with all steps passed.

This PR changes errors handling to leverage closest step to communicate hook failure.

For the After scenario hook, errors are added to the last evaluated step.
For the Before scenario hook, errors are added to the first step.
