Forgot to raise ModuleNotFoundError when None is found in sys.modules. This led to introducing the C function PyErr_SetImportErrorSubclass() to make setting ModuleNotFoundError easier. Also updated the reference docs to mention ModuleNotFoundError appropriately. Updated the docs for ModuleNotFoundError to mention the None in sys.modules case. Lastly, it was noticed that PyErr_SetImportError() was not setting an exception when returning None in one case. That issue is now fixed.
