This commit solves 2 problems in the list view:
- incorrect label for a column
- the label in the optional column dropdown can be different than
the label of the displayed column
When converting the list view, we used the displayName of the widget
and not its label.
In order to improve the consistency between the labels in the optional
column dropdown and the associated columns, we decided to use the same
label.
