Fix getAllPermissionWithProtectionLevel().

This method was only used by PermissionPolicyService, but the
implementation didn't take protection flag into account and thus
didn't watch a lot of runtime permissions (e.g. location
permissions). Tests were passing probably because most of the time app
op change is triggered at the same time.
