PublishMessage differences between .NET and Python

[lokitoth]

PublishMessageAsync on the .NET side sends a message to all agents, including the sender (so if sender also handles messages of that type, it will receive the message).

In Python, this is explicitly avoided (https://github.com/microsoft/autogen/blob/main/python/packages/autogen-core/src/autogen_core/_single_threaded_agent_runtime.py#L376-L379):

# Avoid sending the message back to the sender
if message_envelope.sender is not None and agent_id == message_envelope.sender:
    continue

What should the desired behaviour be here?

Agent should not receive its own message. It complicates things for developers.
