Bug: Set ToolCallBehavior.allowAllKernelFunctions(false) doesn't work for getStreamingChatMessageContentsAsync

Describe the bug
I try to invoke toolcall myself in a streaming chat.
I have learned that how to invoke a toolcall in an non-streaming chat. like

        Kernel kernel = Kernel.builder().withAIService(ChatCompletionService.class, chatCompletionService)
                .withPlugin(KernelPluginFactory.createFromObject(this, "time"))
                .build();

        chatCompletionService
                .getChatMessageContentsAsync("what time is it now?", kernel, InvocationContext.builder()
                        .withToolCallBehavior(ToolCallBehavior.allowAllKernelFunctions(false))
                        .build())
                .block()
                .stream().filter(it->it instanceof OpenAIChatMessageContent<?>)
                .map(it->((OpenAIChatMessageContent)it))
                .forEach(it->{
                    System.out.println(it.getToolCall().size());
                });

As you can see, I can get the toolCall value;

but when I change to an streaming chat, like

        Kernel kernel = Kernel.builder().withAIService(ChatCompletionService.class, chatCompletionService)
                .withPlugin(KernelPluginFactory.createFromObject(this, "time"))
                .build();

        chatCompletionService
                .getStreamingChatMessageContentsAsync("what time is it now?", kernel, InvocationContext.builder()
                        .withToolCallBehavior(ToolCallBehavior.allowAllKernelFunctions(false))
                        .build())
                .filter(it->it instanceof OpenAIStreamingChatMessageContent<?>)
                .map(it->(OpenAIStreamingChatMessageContent)it)
                .doOnNext(it->{
                    System.out.println(it.getToolCall().size());
                }).subscribe();

the toolCall will always be an empty array.

从 getStreamingChatMessageContentsAsync 开始，并使用 issue 中 ToolCallBehavior.allowAllKernelFunctions(false) 的示例，将其行为与 getChatMessageContentsAsync 进行比较。跟踪 OpenAIStreamingChatMessageContent 如何公开工具调用；完成的标准是流式结果包含预期的工具调用数据，而不是空数组，并为此复现提供 coverage。
