SecurityException at startup when getting Bluetooth bonded devices

This crash has been reported by Google Play but not by our crash reporter, perhaps because it happens early in the app lifecycle.

  • Android version: 13
  • Briar version: 1.4.15
  • Phone models: Google raven, panther and bluejay

AndroidSecureRandomProvider calls getBondedDevices() at startup to feed the entropy pool. We added a permission check for Android 12, but apparently it's not always effective.
