There's this complicated back and forth between the listview and
the column chooser.  Work happens in both and it gets confusing
and creates unnecessary complexity.  It also will cause problems
in a future commit where we may want to revert changes that were
made but the list-view doesn't know about that.

Have the column-chooser load in all of the information, and set
the information.  The list-view is merely notified of the changes
for display purposes.
