[Bug] 在一段旧会话中删除消息会删除意外的内容

[Erimus-Koo]

• 一段旧会话，对话结束。并新建对话。
• 过段时间重新载入
• 跳到旧会话，想删除一些不重要的内容
• 问题1：只能删AI的，不能删自己的
• 问题2：在若干次删除之后，发现被删的会话不见了，不想删的也被删了。并且自己的话也不见了。

重试之后比较难复现，可能和网络状态有关。

但删除对话，AI的和自己发出的最好能单独控制。现在删AI的会自动删自己的。

Title: [Bug] Deleting messages in an old conversation deletes unexpected content

• An old conversation, conversation ended. and create a new conversation.
• reload after a while
• Skip to old session, want to delete something unimportant
• Question 1: You can only delete AI's, not your own
• Question 2: After deleting several times, I found that the deleted sessions disappeared, and the ones I didn't want to delete were also deleted. And his own words disappeared.

It is difficult to reproduce after retrying, which may be related to the network status.

But to delete the dialogue, it is best to control the AI's and its own. Now those who delete AI will automatically delete their own.
