### Describe the Bug

```ts
import { drizzle } from "drizzle-orm/sqlite-proxy"

drizzle((query, values, method) => {
if (method === 'get') {
return { rows: [] /* should use falsy value here to indicate no rows instead */ }
}
}, schema)
```

if returns `[]` as rows a db query like `db.query.table.findFirst({ columns: {id: true} })` will return `{id: undefined}` even if the row does not exist
