undefined method `to_model' for nil:NilClass

Hi!

We are using the enumerize gem along with the activeadmin gem, which makes use of formtastic. A number of our forms do not provide an object, like so:

panel 'Do something awesome' do
  active_admin_form_for(
    '',
    method: :post,
    url: awesome_admin_user_path(user)
  ) do |f|
    f.inputs do
      f.input :awesome_id, as: :select
      f.input :other_awesome_thing
    end
    f.submit 'Submit me!'
  end
end

With an update of enumerize from 2.1.2 to 2.2.0, we now get the error in the title when we render these views. I've tracked it down to a change in lib/enumerize/hooks/formtastic.rb on line 8.

I have downgraded our version to 2.1.2 for the time being, but would appreciate your recommendation on whether this is a bug, or we are using forms in an unusual manner that isn't compatible with the changes in enumerize.

Thank you!

@millenniumiguana hey! Thank you for reporting this. I've fixed this in master branch. Could you please test it? If everything is ok we'll probably release a new version with this fix.
