    Add debug info on how many matching accounts a miner found
    
    This is sometimes useful when trying to figure out why a miner doesn't
    work.
    
    The messages are written with g_message(), thus they are only written
    to stdout when G_MESSAGES_DEBUG=all is set in the environment.
    
    Example output:
    
      Gom-Message: Found 2 account(s) of type 'facebook' in the GNOME Online Accounts database.
