Double remote call on DefaultChatClient with content and chatResponse

Bug description
In DefaultChatClient#DefaultCallResponseSpec (also in streaming) call chatResponse or conent trigger the remote call twice.

Environment
Spring AI version M5 confirmed also on main

Steps to reproduce
simply call chatResponse and content and double remote service is invoked

Expected behavior
per "DefaultCallResponseSpec" access to same response (memoized)

Minimal Complete Reproducible example

var response = chatClient.prompt()
		.advisors(new ReReadingAdvisor())
		.call();
response.content();
response.chatResponse();

Start at DefaultChatClient#DefaultCallResponseSpec and inspect the corresponding streaming response path. Reproduce the example by calling content() and chatResponse() on the same response, then verify that each path invokes the remote service only once and returns the same memoized response.
