Print Preview: Remove destination list tooltips

These tooltips do not exist in the original UI and were accidentally
added to the new one. Since the text is identical to the displayed
title, there is no reason for them to exist. Remove them by
renaming the "title" property to "listName", as the title attribute
is used to create tooltips.
