[Script] Update expressions when changing effect name.

I just tried autoFixExpressions() and it seems to work:

var myLayer = app.project.activeItem.layer(1);
myLayer.property("Effects").property(1).name = "New Name";
app.project.autoFixExpressions("Slider Control","New Name");

You would need to address effects by there internal matchname nad keep track of the UI name in your own script with all the extra baggage that brings with it like the necessary string processing.
