Fixes for division. Not allowing class Division to represent a
division of a tensor w.r.t a scalar anymore, wrapping A/b as
as_tensor(A[ii]/b, b) instead.

Added check for potential bug:
a = u[i]*v[i] # => IndexSum(..., i), no free indices
b = a.dx(i) # => SpatialDerivative(IndexSum(..., i), i), free index i
moving the derivative inside the sum would make a
summation over the derivative index which isn't right.
