[Downloads UI] Fix selection toggle for updated items

When a download item is updated, its toggle state should carry over
from the previous DownloadHistoryItemWrapper. This fixes a bug
where a selection remained established if it the Download UI was
opened in two windows and a selected item in one window was
removed from the other window.

Also fixes some variable naming in SelectionDelegate.java
