Fix bookmarks widget not updating

[ahmedre]

This patch fixes a bug where the bookmarks widgets were no longer being
updated due to the recent refactor of bookmarks. Since the deprecated
BookmarkModel was being watched for changes, and since most new code
updates BookmarksDao instead, the widget never got the changes. This
patch fixes it so that the widgets update whenever either get updates.
