Issues with LocationAccessPolicy and getAllCellInfo

**Describe the bug**

A message appears on the device from time to time stating "Please fix this app". In the log I find:

```

**System**

Android Version: 11
Custom ROM: [LineageOS for microG](https://lineage.microg.org/) 18.1

**Additional context**

n/a

Reproduce on Android 11 with Mozilla Location Service enabled, then trace the LocationAccessPolicy calls around getAllCellInfo and getCellLocation, including the USettings request and IchnaeaBackendService log. Done means the described setup no longer shows the “Please fix this app” message or the corresponding LocationAccessPolicy errors.
