    cal-config-webcal: Fix error in a tranform function.
    
    When writing a GBindingTransformFunc for a bi-directional binding in the
    reverse direction, the "source" and "target" properties of the GBinding
    are flip-flopped wrt the transform function.  That always throws me.
    
    Just pass the ESource to the tranform function to avoid this confusion.
