Failure of container in an app with multiple containers not shown in the app entity

[johnmccabe]

Deployed a failing app yaml (mariadb container is failing for in this case), and see the following via the console, note the failure of the container is shown correctly in the docker infrastructure but not in the application.

Observed this with a build of #272.

Yaml used:

location: dc
services:
- type: docker:mariadb:5.5
  id: db
  env:
    MYSQL_ROOT_PASSWORD: "hellooooooooo"
- type: docker:wordpress:4.4
  id: wordpress
  links:
  - $brooklyn:component("db")
  openPorts:
