Bug in hessian structure

Oh, I think the problem comes from the model actually. I did the following (a bit nervous) test:

julia> using NLSProblems, NLPModels

julia> nlp = hs06()

julia> hess_structure(nlp)
([1, 267043088], [1, 167116808])

julia> hess_structure(nlp)
([1, 331019536], [1, 269359968])

julia> hess_structure(nlp)
([1, 331019536], [1, 167149984])

julia> hess_structure(nlp)
([1, 331019536], [1, 167150048])

julia> hess_structure(nlp)
([1, 5124065472], [1, 5124065472])
