Fix incorrect calculation of number of failed tests in stress-test.ipynb

# Overview

Fix `stress-test.ipynb` incorrectly throw error when there are no errors!

## Changes

- stress-test.ipynb: fix incorrect calculation of number of failed tests (when no tests had any errors it was reporting all 4 had error, regression introduced by PR #81)
- stress-test.ipynb: fix incorrect variable access (class method was using global var `results` instead of `self`, copy/paste error during code refactoring in PR #74)
