    single-item-job: Remove redundant function call
    
    Destroying a TrackerSparqlCursor is enough to close it. No need to
    explicitly close it.
    
    In the following patch, when we convert SingleItemJob to use a
    GAsyncResult based asynchronous API, we can't close the cursor like
    this. The GAsyncReadyCallback will be called in the next iteration of
    the GMainLoop, and strictly speaking we shouldn't call
    tracker_sparql_cursor_get* on a closed cursor. It works today, but
    might not work in the future.
