CI: make Windows CI fail when tests fail

Yury Matveevrequested to merge
fix-windows-pipeline into develop

Closes #730 (closed)

When running Windows tests print failed to .\tests\failed_tests.txt and then run script, which fails if file is not empty

This how it works: https://gitlab.com/tango-controls/test-institute-runners/-/jobs/11906584907 (I made one test failing)
