Subject: Make sure that the sort order is correct after renaming

KFileItemModel::setData() should not only cause a resorting when the
sort role is changed. The name is always used as a fallback if the sort
role of multiple files is equal, therefore, renaming a file can change
the correct order of the files even if the files are not sorted by
"name".

Unit test included.
