[Bug]: Possible race condition when restarting position updates after timeout

### Please check the following before submitting a new issue.

- [X] I have searched the [existing issues](https://github.com/baseflow/flutter-geolocator/issues).
- [X] I have carefully [read the documentation](https://github.com/Baseflow/flutter-geolocator/blob/main/geolocator/README.md) and verified I have added the required platform specific configuration.

### Please select affected platform(s)

- [X] Android
- [ ] iOS
- [ ] Linux
- [ ] macOS
- [ ] Web
- [ ] Windows

### Steps to reproduce

My app uses Geolocator in a background isolate (with flutter_foreground_task). In the main Isolate, Geolocator is used to request/check permissions. In the background isolate, the position stream is used. To handle possible stale states, the position stream is requested with a timeout, and the position stream is restarted immediately after timeout occurs. For details, see code sample.

### Expected results

Location stream restarts as expected.

### Actual results

The location stream starts, but doesn't emit any positions. The following series of log messages occurs:
```
2024-12-18 17:54:36.747 4341-4341 FlutterGeolocator Geolocator position updates started
2024-12-18 17:54:36.751 4341-4341 FlutterGeolocator Geolocator position updates stopped
2024-12-18 17:54:36.751 4341-4341 FlutterGeolocator There is still another flutter engine connected, not stopping location service
```

### Code sample

Code sample

```dart
Stream _startGeoLocator() async* {
late final LocationSettings locationSettings;
if(Platform.isAndroid) {
locationSettings = AndroidSettings(
accuracy: LocationAccuracy.best,
forceLocationManager: true,
intervalDuration: Duration(seconds: 1),
timeLimit: _gpsTimeout, // 10 minutes
);
} else {
locationSettings = AppleSettings(
accuracy: LocationAccuracy.bestForNavigation,
activityType: ActivityType.automotiveNavigation,
allowBackgroundLocationUpdates: true,
showBackgroundLocationIndicator: true,
pauseLocationUpdatesAutomatically: false,
timeLimit: null, // no timeout on iOS, as unsubscribing from location updates may allow the device to sleep
);
}

bool timeout = false;
do {
timeout = false;
try {
await for (final position in Geolocator.getPositionStream(locationSettings: locationSettings)) {
yield position;
}
} on TimeoutException {
timeout = true;
// with this delay enabled, the problem doesn't occur and the Geolocator stream emits positions as expected.
// await Future.delayed(Duration(seconds: 5));
}
} while (timeout);
}
```

```

Start by reproducing the issue with getPositionStream, AndroidSettings, a timeout, and an immediate restart in a background isolate. Inspect the Android position-update lifecycle around the logged start/stop messages and the connected-engine handling. Done means the restarted stream emits positions without requiring an artificial delay.
