[Bug]: The intial agent in swarm did not get the initial message

[hughlv]

Describe the bug

Here is the notebook to reproduce this issue:

https://github.com/dustland/roboco/blob/main/notebooks/empty_message_in_swarm.ipynb

When I call initiate_swarm_chat with messages either as an array of Message object or a plain str, the initial_agent passed to this function did not get the message, which cause the loss of the context. I guess it's essential to pass such message to generate_reply to get the correct response.

I'm not quite sure this is a bug or not. Please shed some light as it has blocked my project.

Steps to reproduce

Run this notebook can see it reports the initial agent in the swarm did not get the message:
