subtyping regression

[JeffBezanson]

julia> Type{Union{Int,Void}} <: Type{Union{T,Void}} where T
true

julia> Type{Union{Ref,Void}} <: Type{Union{T,Void}} where T
false

Both are true in 0.6. Probably an artifact of one of the recent subtyping fixes.

fixed on master. Edit no it's not. I misread this horribly.

Should have a test before close
