No js eligibility

can be moved to view helper:
```
module FormHelper
  def step_link_css_class(form)
    'step-current' if step == form.steps.first && params[:action] != 'eligibility'
  end
end
```

then:
```
li.js-step-link.js-step-condition data-step="step-#{step.title.parameterize}" class=(step_link_class(form))
```
