Move token_randomness config to Model::Config in initializer template (…

…#375)

Move `token_randomness` config to the user module.
Before it was placed in the template into the controller module, which leads to an error if configured:

```ruby
NoMethodError:
  undefined method `token_randomness=' for module Sorcery::Controller::Config
```
The attribute is part of the `Sorcery::Model::Config` module though: https://github.com/Sorcery/sorcery/blob/d8ce48a407d0b24ed20c8c8bd5010c9b084cd1b0/lib/sorcery/model/config.rb#L41
