    Don't ref/unref connection repeatedly in calendar code.
    
    We hold a ref on it via cbews->priv, so this shouldn't be needed.
    
    I suspect this was causing the stray unref of cnc which caused problems
    when we fixed the GSimpleAsyncResult leak. Before we fixed the leak, those
    leaked objects would each have a reference on the connection and would
    mask the problem.
