[gnome-photos/wip/rishi/tracker3: 2/4] Remove unnecessary {{item_where}} snippets

[Debarshi Ray <debarshir src gnome org>]

commit af8a4a8682ee32c9b7e02412a545896b54077e09

    Remove unnecessary {{item_where}} snippets
    
    The {{item_where}} snippet is used to show the contents of a collection
    in the COLLECTION_VIEW mode. This mode uses the "all" SPARQL template,
    and therefore the {{item_where}} is unnecessary in all the other
    templates.
    
    A subsequent commit will port to Tracker 3, where the SPARQL templates
    would have to aggregate metadata from different Tracker endpoints.
    Since an item and its collection might belong to different endpoints,
    not having the unused {{item_where}} snippets can greatly simplify the
    SPARQL.
