    Lastfm: avoid unnecessary wait when submitting successful scrobbles
    
    In the case where everything was successful but there are still entries in
    the queue to submit, the overall connection state was set to 'Idle'.
    
    This meant that on the next interval we would realize that we had tracks to
    submit and then set the state to 'NeedTransmit'. This was an unnecessary
    interval step and made Banshee wait a bit before attempting to submit the
    rest of the queue.
