project-name & project-version not being set

I'm using the latest version of documentation.js (v4.0.0-beta.18) , node.js version 7.7.1, npm version 4.3.0 on windows 10.

The command to generate docs is: `documentation build lib/*.js -c documentation.yml -f html -o docs`

I am working on a project generating documentation and it seems that the version doesn't get picked up automatically nor the name.

A snippet of the package.json
```json
{ "name": "myProject",
"description": "description for myProject",
"version": "5.0.0-beta.3"
}
```
I can however set the `project version` via `--project-version` and `documentation.yml` with:
```yaml
project-version:
- 5.0.0-beta.3
```

`project-name` seems to not be set with all of those methods.

I tried searching to see if this was a known issue but didn't see anything come up. Would be great if I could set these values somehow 👍
