Since commit [1], properties can be displayed in list views. However,
when switching from a kanban view showing the properties to a list view
that should be showing the same properties, these are not shown.
This happens because the model in the kanban controller currently uses a
reference of the fields. When loading the list view, the properties are
thus already in the fields, and they are skipped when trying to apply
them.
This commit solves the issue by working with a copy of the fields in the
kanban controller, as the list controller does since commit [1].
