Legacy evaluator name is incorrect

[akshaylive]

Suppose we have an evaluator:

{
  "fileName": "evaluator-default.json",
  "id": "038038f6-46d0-4aa3-b19c-9b68fb7395b4",
  "name": "My LLM Judge Evaluator",
  "description": "",
  "category": 1,
  "type": 5,
  "prompt": "ExpectedOutput:\n{{ExpectedOutput}}\n----\nActualOutput:\n{{ActualOutput}}\n",
  "model": "same-as-agent",
  "targetOutputKey": "*",
  "createdAt": "2025-11-07T01:16:33.467Z",
  "updatedAt": "2025-11-07T01:16:33.467Z"
}

If we load the evaluator and access it's name, it always shows "LegacyLlmAsAJudgeEvaluator".

data = {...} # load from file
evaluator = EvaluatorFactory().create_evaluator(data, None, "")
assert evaluator.name == "My LLM Judge Evaluator"
