    test(lib_git_auth): warnings changed output
    
    Tested string not found because of 'SAWarning: relationship' messages in the output.
    They are caused by changes in SQLAlchemy, as workaround until those warnings are fixed:
    Test statement reduced to the part that still can be identified.
