The RenameDialog::slotResult() slot is currently never called because
the dialog is deleted first, due to the usage of the WA_DeleteOnClose
attribute. This breaks the scroll-to-renamed-file feature when the
inline renaming is disabled.
Instead of deleting the dialog on close, we can use deleteLater() when
we are sure the dialog has actually finished its job, which is when the
KIO move job emits the result signal.
