declare overlap as expected for CFV MVD, no longer ignored due to volume name change

Not sure how the test managed to pass when we introduced the new MVD.
Could be because a "new" setup is not tested while a "changed" setup is, as we did not introduce new setups since 3-4 years, to be confirmed later (e.g. if/when we introduce a 2025 mCBM setup)
