When the model_worker starts, the template parameter settings seem invalid.

Nobody has claimed this yet.

My startup command is
```
python -m fastchat.serve.vllm_worker --model-path TheBloke/Nous-Capybara-34B-AWQ --trust-remote-code --tensor-parallel-size 2 --quantization awq --max-model-len 8192 --conv-template manticore
```
But I got the following output
```

The settings '--conv-template manticore' here are not effective, but got an one_shot template.
