Don't set fake msg_id in resent messages

Setting the msg_id to `u32::MAX` is hacky, and may just as well break
things as it may fix things, because some code may use the msg.id to
load information from the database, like `get_iroh_topic_for_msg()`.

From reading the code, I couldn't find any problem with leaving the
correct `msg_id`, and if there is one, then we should add a function
parameter `is_resending` that is checked in the corresponding places.
