onDowngrade fix: avoid dropping system tables such as sqlite_sequence which may not be dropped. modify the test to have an auto-increment field so that the sqlite_sequence table is generated, this would reproduce the exception found in the bug. Make the onDowngradeTest parametrized on relevant flags
