Bug for slur and (not) restored accidental

[Rutger Hofman]

% If a slur spans a bar, and after the bar a note has an accidental
% as-per key, and the note before the bar is the same but natural-ed,
% an accidental should be printed for the note after the bar.
%
% The first line in the example should be identical to the second line.
% This is irrespective of accidentalStyle.
