Address additional code review feedback

- Use ASSERT_TRUE for varItem and controller in addIntegral test to remove nested if blocks
- Add dynamic_cast to OperationBase to properly access type() method
- Rewrite makeVariablesConsistent test to use GodleyIcon and verify flowVars/stockVars population
- Improve garbageCollect test to verify flowVars, stockVars, equations, integrals are non-empty before and empty after
- Remove unnecessary if guards in populateMissingDimensions test
