robo ci:travis-prepare wants everything to be Arrays

[trinitronx]

Ran into a bug using a .travis.yml file that didn't specify everything as an Array. To reproduce, just check out Bash-it/bash-it@master, and use their simple .travis.yml:

 ~/src/pub/bash-it ± |master ✓| $ cat .travis.yml
sudo: false
install: git clone --depth 1 https://github.com/sstephenson/bats.git
script: PATH="./bats/bin:$PATH" test/run
language: c

 ~/src/pub/bash-it ± |master ✓| $  robo ci:travis-prepare

Changing everything to arrays, and forcing it to use language: php seems to make robo mostly happy:

 ~/src/pub/bash-it ± |master ✓| $ cat .travis.yml
sudo: false
before_install:
  - bash --version
install:
  - git clone --depth 1 https://github.com/sstephenson/bats.git
script:
  - PATH="./bats/bin:$PATH" test/run
language: php
php:
  - 5.6.14

Seems to still throw an error on src/Command/Travis/Prepare.php:59, but running robo ci:run appears to partially work:

 ~/src/pub/bash-it ± |master ✓| $ robo ci:run 5.6.14

It looks like RoboCI makes a lot of assumptions. It appears to assume you're testing a PHP app with mysql and postgresql containers. I just wanted to try it out using a basic bash container testing with bats. Not sure if this is an intended use, but it seems like a simple enough case to support.
