Verification reporting: Subsumptant rows hides Deficient rows

If the table contains Deficient rows and Subsumptant rows are added, then the messages about Deficient rows disappear.

To reproduce:

1. Open the example mortgages project
2. Navigate into the package: mortgages.mortgages
3. Upload there the attached GDST
4. You will see GDST with 4 rows
   • There will be verification message about Subsumptant rows
5. Remove the rows: 3, 4
6. Save and reopen the GDST
   • There won't be verification message about Subsumptant rows
   • There will be verification messages about Deficient rows
   • Messages about Deficient rows are expected also before deleting rows: 3, 4

The same holds true also if the rows 3 and 4 are Conflicting or Redundant.
