Re-order send/receive

Browse source 
There are no guarantees that send_message and receive_massage do not block
the flow of execution. Therefore they must be paired between Alice/Bob, one
send to one receive in the correct order.

Define Alice to call `receive_message` first, with Bob sending the message. Do
this because we are expecting Alice to be have a well known address, there is no
currently such assumption for Bob.
