Yes, there definitely is such a trope. But this would leave "missing supertrope": it works much the same way with Giant Mutant Fleas, and other critters, up to degenerate descendants of the former crew. E.g. WH40k hulks, and even less-staffed used ships, are full of such things. But the name would not quite fit even your version. And there would be inevitable overlap. Perhaps something like "Derelict Denizens"? With "Ghost Ship" left as disambiguation.
