Rolify app logs cli/command

[milk1000cc]

App logs filtered by roles (e.g., mrsk app logs --roles=job) are not filtered correctly.
Also, logs are not output properly when the same service runs on the same host with different roles.

When config/deploy.yml is

service: app

servers:
  web:
    - 1.1.1.1
  job:
    hosts:
      - 1.1.1.1
    cmd: bin/jobs

current output of mrsk app logs is

INFO [b92537f1] Running docker ps --quiet --filter label=service=app | xargs docker logs --tail 100 2>&1 on 1.1.1.1
App Host: 1.1.1.1
