Wrong history messages

[mayestik1]

Describe the bug
The message history has an incorrect structure when calling tools. OpenAI returns the following error:
An assistant message with 'tool_calls' must be followed by tool messages responding to ea (truncated...)
Additionally, I have observed that the first agent message appears twice.

To Reproduce
To reproduce the behaviour it is needed to implement DatabaseChatHistory.
My testing code is:
`

public function __construct(string $chat_id, int $contextWindow = 50000)
{
    parent::__construct($contextWindow);

    $this->chat_id = $chat_id;
    $this->init();
}

protected function init(): void
{
    $value = DB::table('CAS_CallService')->where('CAS_ID', '=', $this->chat_id)->value('CAS_History');

    if ($value) {
        $messages = \json_decode($value, true);
        $this->history = $this->unserializeMessages($messages);
    }
}

protected function storeMessage(Message $message): ChatHistoryInterface
{
    $this->updateHistoryColumn();

    return $this;
}

public function removeOldestMessage(): ChatHistoryInterface
{
    $this->updateHistoryColumn();

    return $this;
}

protected function clear(): ChatHistoryInterface
{
    DB::table('CAS_CallService')->where('CAS_ID', '=', $this->chat_id)->update(['CAS_History' => null]);
    $this->history = [];

    return $this;
}

protected function updateHistoryColumn(): void
{
    DB::table('CAS_CallService')->where('CAS_ID', '=', $this->chat_id)->update(['CAS_History' => json_encode($this->jsonSerialize())]);
}

}
`

Expected behavior
Agent cannot load messages history from DatabaseChatHistory provider based on FileChatHistory

It's not clear the expected behaviour:

"Agent cannot load messages history from DatabaseChatHistory provider based on FileChatHistory"
