ActivityScenario.getResult() occasionally delays 45 secs

Nessuno ha ancora preso questa issue.

### Description

Using the new `ActivityScenario` for our tests. Sadly in various occasions the `getResult()` will wait 30 seconds until it returns successfully. This behavior is not deterministic as sometimes it works again.

In both cases the result will be delivered successfully.

In cases the `getResult()` waits for 45 seconds the tested activity is already finished and the empty activity with black background is shown.

### Steps to Reproduce

The steps in our project to reproduce:

`launchActivity`
```
ActivityScenario.use{
// do the testing
// ui code finishing the activity

// retrieve `result`
result.checkResultData()
}
```

### Expected Results

It would not wait for 45 seconds but less time before retrieving the result data

### Actual Results

It freezes randomly for 45 seconds before successful result data is retrieved

### AndroidX Test and Android OS Versions

- 3.3.0-rc01
- Android 11, but also happening on Android 10

### Link to a public git repo demonstrating the problem:

Inizia da ActivityScenario.getResult() e dal flusso launchActivity descritto nel report, quindi riproduci il ritardo intermittente su Android 10 o 11. Traccia l’attesa fino alla consegna del risultato dell’activity e verifica che il risultato venga restituito senza la pausa di 45 secondi segnalata; l’issue è obsoleta e non ha alcuna pull request collegata.
