Shows wrong "unplayed" count after deleting unplayed files

Binary package hint: miro

If you have multiple unplayed video items in the library, when you delete the item directly (rather than selecting "Mark as Played" first) it removes the item but doesn't update the count.
Expected result: Count is automatically updated
Actual result: Video library says it has 22 unwatched items - but they don't show up in any of the view filters (i.e. ghost items)
