#11871: Fix cellular automata function

------------------------+---------------------------------------------------
In #9623, lots of interacts were added to the library. Unfortunately, one
(based on [http://wiki.sagemath.org/interact/misc#Cellular_Automata this
wiki page by Pablo Angulo and Eviatar Bach]) was "optimized" a bit too
much. We need to replace
{{{
for k in range(N-j, N+j+1):
}}}
by
{{{
for k in range(0,2*N):
}}}
as in the original.
One can test this by making sure the outputs are the same as at
[http://mathworld.wolfram.com/ElementaryCellularAutomaton.html the
MathWorld site] for this. Thanks to jhpalmieri for discovering this in
unrelated testing at #9623.
