.Net: Bug: 在调用GetStreamingChatMessageContentsAsync方法时如果传入了executionSettings的参数时流式输出就会失效

[landonzeng]

Describe the bug
当我执行以下代码时：

 var endpoint = new Uri("http://localhost:11434/v1/");
 var modelId = "qwen2.5:14b";

var httpClient = new HttpClient();
var builder = Kernel.CreateBuilder()
    .AddOpenAIChatCompletion(modelId: modelId!, apiKey: null, endpoint: endpoint, httpClient: httpClient);
var kernel = builder.Build();

var chatCompletionService = kernel.GetRequiredService<IChatCompletionService>();

var openAIPromptExecutionSettings = new OpenAIPromptExecutionSettings()
{
    ToolCallBehavior = ToolCallBehavior.AutoInvokeKernelFunctions
};
KernelArguments kernelArgs = new(openAIPromptExecutionSettings);
var history = new ChatHistory();
string? userInput;
do
{
    Console.Write("User > ");
    userInput = Console.ReadLine();
    history.AddUserMessage(userInput!);

    var result = chatCompletionService.GetStreamingChatMessageContentsAsync(history, executionSettings: openAIPromptExecutionSettings, kernel: kernel);
    string fullMessage = "";

    Console.Write("Assistant > ");
    await foreach (var content in result)
    {
        Console.Write(content.Content);
        fullMessage += content.Content;
    }
    Console.WriteLine();

    history.AddAssistantMessage(fullMessage);
} while (userInput is not null);

如果chatCompletionService.GetStreamingChatMessageContentsAsync方法传入了executionSettings的参数时流式输出就会失效，如果不传入的话，流式输出是正确的，例如：

chatCompletionService.GetStreamingChatMessageContentsAsync(history,  kernel: kernel);

修改成这样，那么控制台将以流式输出AI回答的内容

Expected behavior
GetStreamingChatMessageContentsAsync能正确按流式输出内容
