    libtracker-data: Do not force cursor column types to be strings
    
    We must propagate the original types, despite converting the
    resultset to string in the topmost select. Fixes warnings in the
    bus backend (seen with several flatpak apps), since it's not as
    lenient as the direct one wrt fetching values with the "wrong"
    vfunc.
