Fix UnboundLocalError in `retrieve.py` due to missing `instance_id` assignment

[MichaelYang-lyx]

There is an issue in /mnt/llm_test/code/yyb/projects/Agentless/Agentless/agentless/fl/retrieve.py where reusing previous retrieval results leads to the following error:

UnboundLocalError: cannot access local variable 'logger' where it is not associated with a value

Issue Details

• The error occurs because the instance_id is not properly assigned before constructing the log file path.
• This can be resolved by adding the following lines at line 28 in retrieve.py:

instance_id = bug["instance_id"]
log_file = os.path.join(
    args.output_folder, "retrieval_logs", f"{instance_id}.log"
)

Steps to Reproduce:

1. Run the script with previously retrieved results.
2. Observe the UnboundLocalError.

Expected Behavior:

• The script should correctly log retrieval operations without raising an UnboundLocalError.

Suggested Fix:

• Assign instance_id and construct the log_file before logging operations.
