    Properly send a 487 on an INVITE we have not responded to if we receive a BYE.
    
    If we receive an INVITE from an endpoint and then later receive a BYE from that
    same endpoint before we have sent a final response for the INVITE, then we need
    to respond to the INVITE with a 487. 
    
    There was logic in the code prior to this commit which seemed to exist solely to 
    handle this situation, but there was one condition in an if statement which 
    was incorrect. The only way we would send a 487 was if the sip_pvt had no owner
    channel. This made no sense since we created the owner channel when we received
    the INVITE, meaning that the majority of the time we would never send the 487.
    The 487 being sent should not rely on whether we have created a channel. Its
    delivery should be dependent on the current state of the initial INVITE transaction.
    With this commit, that logic is now correctly in place.
