    view: fix bug in draw_spaces_tag_foreach()
    
    The goal of the function is to find if a GtkSourceTag is present and
    that uses the draw-spaces property. It must also return TRUE when
    draw-spaces is FALSE, since when it is set, it overrides the global
    setting.
    
    There was no bugs in test-space-drawing because it worked by chance,
    with the condition at where buffer_has_draw_spaces_tag() is called. But
    in the future that code might be modified, or
    buffer_has_draw_spaces_tag() could be used at another place, and a bug
    would be introduced.
    
    The function name buffer_has_draw_spaces_tag() is normally clear enough
    in its meaning...
