Attempt to fix AlertSummaryWidget flaky test (elastic#212107)

Fixes elastic#198102

## Summary

The check that fails is related to status:All
[here](https://github.com/elastic/kibana/blob/main/x-pack/test/observability_functional/apps/observability/pages/rule_details_page.ts#L191):

```
expect(url.includes('status%3Aall')).to.be(true);
```

It seems the status is active from the previous step:
