[JÃrg Billeter <juergbi src gnome org>]

commit f72c460583dc4bb5bf7404d74a8c630da6d50dc8
Author: Cosimo Cecchi <cosimoc gnome org>

    libtracker-data: Implement get_property() for n-columns in SQLite cursor
    
    n-columns is an abstract property, so it should be implemented by all
    the TrackerCursor subclasses
    
    Fixes GB#654407.
