Steps to reproduce

• Prepare any config
• Run universum with shelved file from attachment: python3.7 -u -m universum --no-diff --p4-client TEST_WS-tcagent03 --p4-force-clean

Actually duplicate of #584

Note no adding of REPOSITORY_DIFFERENCE.txt to artifacts.
Most likely, file diff contained non-UTF-8 characters.
