New ambiguity on 1.3

[KristofferC]

While running the package tests for the upcoming 1.3, a new ambiguity in this package was detected:

Matúš: Error During Test at /root/.julia/packages/EntropicCone/it9ca/test/matus.jl:1
  Got exception outside of a @test
  MethodError: intersect(::DefaultPolyhedron{Float64,Polyhedra.Intersection{Float64,SparseArrays.SparseVector{Float64,Int64},Int64},Polyhedra.Hull{Float64,Array{Float64,1},Int64}}, ::MixedMatHRep{Float64,SparseArrays.SparseMatrixCSC{Float64,Int64}}) is ambiguous. Candidates:
    intersect(p::Union{HRepresentation{T}, Polyhedron{T}} where T...) in Polyhedra at /root/.julia/packages/Polyhedra/Su6Kf/src/repop.jl:19
    intersect(p1::Union{HRepresentation{T}, Polyhedron{T}, HRepElement{T,AT} where AT}, p2::Union{HRepresentation{T}, Polyhedron{T}, HRepElement{T,AT} where AT}, ps::Union{HRepresentation{T}, Polyhedron{T}, HRepElement{T,AT} where AT}...) where T in Polyhedra at /root/.julia/packages/Polyhedra/Su6Kf/src/repop.jl:29
  Possible fix, define
    intersect(::Vararg{Union{HRepresentation{T}, Polyhedron{T}} where T,N} where N)

We believe this is a real ambiguity that got detected due to improvements in the Julia type system and thus needs to be fixed in this package.

Seems to also originate from Polyhedra so it might be related to JuliaPolyhedra/Polyhedra.jl#187

True, closing as dup of that one.
