Possible bug in llm_checker's is_joint code path

[rchaks]

In the is_joint code path, the prompt template seems to be hard-coded to the JOINT_CHECKING_PROMPT_Q prompt that requires a question to be passed in:

RefChecker/refchecker/checker/llm_checker.py

Line 87 in bd516af

prompt_template = JOINT_CHECKING_PROMPT_Q

.

However, I think this should be using self.prompt_temp or self.prompt_temp_wq depending on whether question is None just like the non joint checker:

RefChecker/refchecker/checker/llm_checker.py

Line 181 in bd516af

if question is None:
