This restores the workaround in the "for-all-variants" runtime needed for MPS-34340. In mps20241, this problem was hidden because exceptions in checking rules were not reported, and so the removal of the workaround didn't cause any visible issues. In mps20251, exception are thoroughly handled, so the workaround is needed again.
Notes:
org.iets3.variability.artifacts.typesystem.runtimewhich hosts the workaround has been moved from IETS3.Core to IETS3.Opensource in 2025. So the workaround could not be just restored, but had to be re-added by copy&paste.TwoActualRoots), which checks that the workaround is working correctly. This test needs stuff from IETS3.Core, so it could not be migrated to IETS3.Opensource together with theorg.iets3.variability.artifacts.typesystem.runtimesolution. Thus, we need a companion PR in IETS3.Core to adapt the test.This solves #1709.
