Quick calculation bar updates wrong column when using aliases

Description

The quick calculation bar does not work as expected when trying to update a field that has an alias set.
Instead of updating the selected column, it updates the first column in the table.

This affects both 2.4 and master.

This can lead easily to data loss if the user does not confirm the update.

To reproduce the problem add a layer (I have tried with shapefiles and postgis table), and try to update one of the fields (not the first one) using the quick calculation bar. Now Go to the layer properties > fields and set an alias for the same field.

Going back to the attribute table, you will see that the field selection combo box as changed (as it should) and trying to update the field will no longer work.

I would set this as a blocker, because it causes a severe data corruption/lost. Feel free to downgrade it.
