fix: handle both ival 0 and -1 cases in AlterTableCmd context for SET STATISTICS

- Fixes original-upstream-alter_table.test.ts and original-upstream-foreign_data.test.ts
- Both ival=0 and ival=-1 should convert to empty Integer objects in AlterTableCmd context
- Now at 254/258 tests passing with only syntax error failures remaining
