[sql] select queries are still blocked and not executed concurrently (sqlite)

Even with this fix https://github.com/tauri-apps/plugins-workspace/pull/1972 implemented to answer this issue https://github.com/tauri-apps/plugins-workspace/issues/1935, after updating to v2.2.0 this code still executes sequentially and not concurrently.

```
console.time("long");
console.time("short");
// This takes 3 seconds
db.select(
"WITH RECURSIVE cte(x) AS (SELECT 1 UNION ALL SELECT x + 1 FROM cte LIMIT 10000000) SELECT count(x) FROM cte;"
).then(() => {
console.timeEnd("long");
});
db.select("SELECT 1;").then(() => {
console.timeEnd("short");
});
```

> [Debug] short: 3395.760ms (Sandbox.tsx, line 41)

Is there something I missed?
