Steps to reproduce

工作流中配置了【知识检索节点】后，调试时没有输出，查看docker-api日志后报错如下：

Exception in thread Thread-78 (embedding_search):
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/threading.py", line 1016, in _bootstrap_inner
    self.run()
  File "/usr/local/lib/python3.10/threading.py", line 953, in run
    self._target(*self._args, **self._kwargs)
  File "/app/api/core/rag/datasource/retrieval_service.py", line 133, in embedding_search
    data_post_processor = DataPostProcessor(str(dataset.tenant_id), reranking_model, False)
  File "/app/api/core/rag/data_post_processor/data_post_processor.py", line 16, in __init__
    self.rerank_runner = self._get_rerank_runner(reranking_model, tenant_id)
  File "/app/api/core/rag/data_post_processor/data_post_processor.py", line 33, in _get_rerank_runner
    rerank_model_instance = model_manager.get_model_instance(
  File "/app/api/core/model_manager.py", line 228, in get_model_instance
    return self.get_default_model_instance(tenant_id, model_type)
  File "/app/api/core/model_manager.py", line 250, in get_default_model_instance
    raise ProviderTokenNotInitError(f"Default model not found for {model_type}")
core.errors.error.ProviderTokenNotInitError: Default model not found for ModelType.RERANK

然后在系统配置中添加了rerank模型后就可用了。
但是页面上提供了Rerank模型的开关，是否应该在关闭时不去初始化Rerank模型？
