Juju-deployer skips deployment to some machines when multiple are specified with 'to:'

[Tim Kuhlman]

Using a bundle file like the following simplified version:

controllers:
  series: "xenial"
  machines:
    "0":
      series: "xenial"
      constraints: arch=amd64
    "1":
      series: "xenial"
      constraints: arch=amd64
    "2":
      series: "xenial"
      constraints: arch=amd64
  services:
     ubuntu:
      charm: ubuntu
      to: ["0", "1", "2"]

After a deploy the ubuntu service is running on machine 0 but not on machine 1 or 2.

This is running with Juju 2.0-rc1 and the latest juju-deployer from the ppa ppa:tvansteenburgh/ppa

It affected me too, in my case it was picking the machines randomly where I also specified 3 units. Sometimes it deploys all the units to one machine and sometimes it deploys on two machines with two units on a single machine.
