Iterators for matrix_space broken

Iterators for 0-dimensional matrix spaces should not fail but return the zero element and nothing for subsequent calls
julia> k = GF(3);
julia> m = matrix_space(k, 0, 1);
julia> for x in m ; end
ERROR: BoundsError: attempt to access 0-element Vector{Nemo.fpField} at index [1]
Matrix algebras over finite rings should define an iterator:
julia> m = matrix_algebra(k, 1);
julia> for x in m; end
ERROR: MethodError: no method matching iterate(::AlgMat{fpFieldElem, fpMatrix})

The first issue really is an issue in AbstractAlgebra; I've posted a fix at Nemocas/AbstractAlgebra.jl#1527
The second issue indeed is indeed Hecke specific.
