Corrections

I ran the following in order to ensure I didn't break any unit-test:
```Bash
bundle install
bundle exec rake spec
```
Result was fine, thus if unit-tests are complete, it shouldn't break anything. I was using rvm with ruby 2.1.5 installed.

Effects for those modification:

- run without any error for a "normal" installation
- main functionalities are working otb after first puppet run
- a better order for resources inside the module
