Better error handling

Please check this issue, that killed the checkout process in my case, preventing sales.
Although the parcelPro module was disabled in Stores->Configuration->Sales->Delivery Methods...

CRITICAL: Exception: Deprecated Functionality: strtolower(): Passing null to parameter #1 ($string) of type string is deprecated in /[...]/vendor/parcelpro/shipment/Observer/Shipment.php on line 51 in

What happens there:
if (strtolower($config["auto_status"]) == 'pending') {

There's two things wrong here.

1. The dropdown values for statusses weren't set yet. So there is no error handling for that here.
2. The module was not enabled in the admin, so why is all this fired at all
