Fix FiniteDifferenceStencilDerivation.rotate_weights_and_apply
Recent Numpy version do not support conversion from arbitrary iterables if they have the attribute shape.
The FiniteDifferncesNotebook fails on my machine since to shape (3,3,3) and sequence of length 27 don't fit together.
I guess that recent Numpy will deprecated construction from arbitray sequences (only list and tuple, and objects with __array__ are allowed).
