The safe_Browsing_service_browsertest.cc code currently has parts that only work with Pver3 database manager. We should switch that to work with Pver4, and ensure Pver4 test coverage is at least as good as Pver3.
One way to measure Pver3 dependencies is to hardcode IsV4OnlyEnabled()==true and then run all the tests. We should ensure pver4 tests are running on the bots before we roll out.
