If you don't typeset the key cancellation when you change to C major, 
there's no
way for the musician to recognize that you did a key change, right? 
Therefore
LilyPond is clever enough to always print the key cancellations to C 
major, no
matter if printKeyCancellation is set or not. If you really want to get 
rid of it
anyway (which means that you have to invent some other method to tell your
musicians that there is a key change), you can use brute force:
\override Staff.KeyCancellation #'stencil = ##f
