After deleting a photo, the "Showing # photos." label doesn't update

1. Open a project with, for example, 8 photos. With no filters on, the label above the thumbnail panel will say "Showing 8 photos."
2. Delete a photo from the project using its thumbnail "Delete" button. Unexpectedly, the label doesn't get updated.

(The label updates after, e.g., changing the sort order.)
