Bug description When we use the chatClient class with "defaultSystem" and "MessageChatMemoryAdvisor", when making the call to OpenAI with a message history, the first element of the array is not of role "system"
Environment Spring AI: 1.0.0-M5 Java version: 21.0.5-zulu
Steps to reproduce I created a chatClient linked to a "defaultSystem" and with the "MessageChatMemoryAdvisor", and checked the order of the messages sent to OpenAI.
Expected behavior The default system message will always be the first message in the array sent to OpenAI.
Minimal Complete Reproducible example Please provide a failing test or a minimal complete verifiable example that reproduces the issue. Bug reports that are reproducible will take priority in resolution over reports that are not reproducible.

Thanks for reporting this issue. I would recommend addressing this together with https://github.com/spring-projects/spring-ai/issues/873, making sure to implement a consistent and predictable strategy for placing system messages across different use cases.
