Replace setExpanded(const QSet<KUrl>&) by expandParentItems(const KUrl&)

The use case of this function (Folders Panel) requires the expansion of
the parent items of a single URL, so it's not needed to handle a full
set of URLs in this function. Moreover, the issue that not only the
parents, but also the URLs themselves were expanded is fixed by this
commit.
