    Csv Importer - Prevent crash if number of saved columns is higher than actually detected ones.
    
    I ran into this while trying to load a utf-16 encoded file
    and loading a saved preset using utf-8. By applying the preset
    the columns in the utf-16 file were no longer detected, but
    the importer was still trying to read from a preset account column.
