Bug 27081: Handle first column (checkboxes) in column settings for lost items report

We are adding one column (the one with the checkboxes) at the beginning
of each row if it's possible to export the report to CSV.
However the column settings were not modified. We need to append one
object representing this column.

Test plan:
To test:
* Create a CSV profile of type SQL for exporting lost items
* Make sure you have some lost items
* Run Reports > Items lost
=> You can hide the notes (last column)
