Well, the whole note has more room because it isn't sharing the measure 
with any other notes.    
But the barline collision is a direct consequence of the extra-offset 
you are applying via StefansStringsOffsets:    (-1 . 0).

I suggest that you may not need these (errorprone) lists of 
spacing constants,    e.g.  you can derive the Y-extent as     
         
 \override Accidental #'Y-extent = #(lambda (grob)
    (ly:stencil-extent (ly:text-interface::print grob) Y))
         
The same goes for X-extent, but here you can apply a correction for 
the inbuilt font padding, similar to my suggestion in         
http://lists.gnu.org/archive/html/lilypond-user/2009-09/msg00339.html      
         
 \override Accidental #'X-extent = #(lambda (grob)
   (interval-translate (ly:stencil-extent 
     (ly:text-interface::print grob) X) -0.5))
         
Feel free to adjust this value of 0.5  -  it was only provisional.  
In fact it should really be scaled for non-default font sizes.
