Not compatible with Gen 3

In Gen 3, the production branch is `master`, but the `Config->onProduction()` does:
```
$prodBranch = $this->onDedicated() ? 'production' : 'master';
```
Which results in `false` while in fact you are on "production".

I don't know if there are variables to check if you are on Gen 3, but that would need to be included in the code.
