Nestjs lifecycle events are not finished as expected with await app.init in before hooks

In the e2e testing codes, app.init did not ensure the execution OnModuleInit.

Sometimes the sample data is filled, sometimes not.

It caused the following tests failed sometime.

it('/posts (GET)', async () => {
      const res = await request(app.getHttpServer()).get('/posts').send();
      expect(res.status).toBe(200);
      expect(res.body.length).toEqual(3);
    });

From the CI build results, this test still failed sometimes even I changed to async/await instead of Rxjs Observable.
