Can't deploy bundle when existing model has subordinates without relations

[Casey Marshall]

Juju 2.3-rc2-xenial-amd64 installed from candidate snap, using manual provider (which is why I really need map-machines=existing...).

When I try to deploy a bundle with --map-machines=existing, I get:

+ juju deploy ./bundle.yaml --map-machines=existing
ERROR cannot deploy bundle: getting application constraints: constraints do not apply to subordinate applications

The bundle contains several applications, relating them to telegraf:

series: xenial
services:
  haproxy:
...
  telegraf:
    charm: "./charms/telegraf"
    series: xenial
    expose: true
relations:
  - [livepatch-health, haproxy]
  - ["livepatch-health:database", "postgresql:db"]
  - ["telegraf:postgresql", "postgresql:db-admin"]
  - ["telegraf:juju-info", "postgresql:juju-info"]
  - ["telegraf:juju-info", "livepatch-health:juju-info"]
  - [livepatch-health, "prometheus:target"]
machines:
  "0":

This works on a 2.3 controller. But it seems to be a problem against older controllers.

We'll look to get this fixed asap.

confirmed with controller and juju version 2.3.1 (2.3.1-xenial-s390x)

I am still experiencing this problem on Xenial with most recent Juju and LXD versions.
