graph saved using JLD2 cannot be loaded on same machine

[sbromberger]

I get warnings and then an error:

julia> g = loadgraph("mgtest1.mg", MGFormat())
┌ Warning: type SimpleGraphs.SimpleGraphs.SimpleEdge{Int64} does not exist in workspace; reconstructing
└ @ JLD2 ~/.julia/packages/JLD2/KjBIK/src/data.jl:1153
┌ Warning: type SimpleGraphs.SimpleGraphs.SimpleGraph{Int64} does not exist in workspace; reconstructing
└ @ JLD2 ~/.julia/packages/JLD2/KjBIK/src/data.jl:1153
ERROR: MethodError: Cannot `convert` an object of type getfield(JLD2.ReconstructedTypes, Symbol("##SimpleGraphs.SimpleGraphs.SimpleGraph{Int64}#400")) to an object of type SimpleGraph{Int64}

(This used to work a while ago; I can't point to when things broke.)

The savegraph code is simply

function savemg(fn::AbstractString, g::AbstractMetaGraph)
    @save fn g
    return 1
end

and the loadgraph code is

function loadmg(fn::AbstractString)
    @load fn g
    return g
end

Also: there's no such thing as SimpleGraphs.SimpleGraphs.SimpleEdge - it's SimpleGraphs.SimpleEdge.

Closing. This requires using LightGraphs.SimpleGraphs to work properly.
