auto loader + `--loader=testdouble` (or quibble) breaks

[connorjclark]

Since the auto loader was added, existing usages via node --loader=testdouble began applying the quibble resolver twice (note: this may only have become true in Node 21+). This causes infinite loops in my use case (might be limited to usage of ?__quibbleoriginal).
