    ide-source-location: protect against negative values
    
    IdeSourceLocation uses a guint as line_offset but
    we often use it with gtk_text_buffer_get_iter_at_line_offset
    which uses a gint, so wrong large offset can turn
    into a negative value and fail
    
    Same for the line number.
