Upgrade to 2025.11 broke dotnet parallel tests

We use “dotnet test” together with the “parallel tests” build feature.
Everything worked fine in 2025.03 but upgrading to 2025.11 broke the parallel test runs.

Error in TC:

Analyzing statistic builds > An error while creating parallel tests. The build will run as single.

Error in TC-Server logs:

Failed to generate dependencies for the parallel tests build feature in build: Build promotion {id=<myid>, configuration={id=<myproject>/bt3_101}}: java.lang.IllegalArgumentException: Comparison method violates its general contract!
