multiple addprocs is order dependent #20011
Description
to add procs on a remote machine as well as the local one, it only works if i do the remote first:
julia> addprocs([("remote-machine",1)])
1-element Array{Int64,1}:
2
julia> addprocs(1)
1-element Array{Int64,1}:
3
i get a connection refused error if i reverse the order:
julia> addprocs(1)
1-element Array{Int64,1}:
2
julia> addprocs([("remote-machine",1)])
ERROR: connect: connection refused (ECONNREFUSED)

this is for julia 0.5 and the latest nightly.
i believe i've reported this before, and i thought at one point it was fixed, but i cannot find any record in the issue tracker.
