Remove traces of version-0 calling convention in src/tutorial/

Support has been removed as of 5ded4bd, but code related to the tutorial
still used it.  Functions using version-1 are already present for some
time in the tutorial, and the documentation mentions them, so just
replace the old version with the new one.
