[BUG] react error handling

[bkj]

If there are no tool calls, this checks if there is parsable JSON:

• If parsable json AND looks like tool call, record as tool call
• If NOT not parsable JSON, record as final answer

But .. if parsable json AND doesn't look like tool call, then nothing happens and the loop continues.

I think needs to be changed to:

try:
    # Check to ensure the content isn't an tool call in the wrong place.
    action_json = json.loads(action.text)
    if isinstance(action_json, dict) and "id" in action_json and "name" in action_json and "args" in action_json:
        action.tool_calls.append(action_json)
    else:
        action.tool_calls.append({
            "id": uuid.uuid4().hex,
            "name": "final_answer",
            "args": {
                "response": action.text
            }
        })
        
except json.JSONDecodeError:
    # Presume content to be a final answer
    action.tool_calls.append({
        "id": uuid.uuid4().hex,
        "name": "final_answer",
        "args": {
            "response": action.text
        }
    })
