fix: prevent RecursionError when pickling Config

Browse Source 
On Python 3.8+ with macOS, the multiprocessing module uses 'spawn' by
default which pickles objects. When pickle.load tries to read
__setstate__ before __dict__ is restored, it hits __getattr__ causing
infinite recursion. Adding a special case for 'settings' prevents this.

Closes #2401
