Attempt to get a record from database without an in-progress transaction

### Version info

**Angular:** 14.2.8

**Firestore:** 9.15.0

**AngularFire:** 7.5.0

**Ionic:** 6.1.9

**iOS:** 16.1.1 iPhoneSE (error also happens on newer versions)

### How to reproduce these conditions

**Steps to set up and reproduce**

* Setup of `app.module.ts`:
```typescript
// ...
import { initializeApp, provideFirebaseApp } from '@angular/fire/app';
import { AngularFireAuthModule } from '@angular/fire/compat/auth';
import { FirestoreService } from './services/firestore.service';
import { AngularFireModule } from '@angular/fire/compat';
import { AngularFirestoreModule } from '@angular/fire/compat/firestore';

@NgModule({
declarations: [
AppComponent // ...
],
imports: [
// ...
IonicModule.forRoot(),
// ...
AngularFireModule.initializeApp(environment.firebase),
AngularFireAuthModule,
AngularFirestoreModule.enablePersistence(),
provideFirebaseApp(() => initializeApp(environment.firebase)),
],
providers: [
FirestoreService,
// ...
],
bootstrap: [AppComponent],
})
export class AppModule {}

```
* sync build to ios device
* lock screen (it's hard to actually reproduce)

### Actual behavior

After the screen gets locked on an iOS device, Firestore gets into an unexpected state and none of the Angular routes that use firebase queries can be accessed anymore. We only query data of our firebase instance, so there shouldn't be transaction issues.

Beginne mit der Einrichtung in app.module.ts, insbesondere mit AngularFirestoreModule.enablePersistence(), und reproduziere das Problem auf einem iOS-Gerät, indem du den Bildschirm sperrst. Vergleiche die Fehler in Firestore 9.15.0 mit den betroffenen Angular-Routen und der Verwendung von FirestoreService; als erledigt gilt die Aufgabe, wenn interne Fehler Firebase-Abfragen und Routen nach dem Entsperren nicht länger unbenutzbar machen.
