Devise token auth tries to send confirmation email even though it is disabled

Hi,
I followed the instructions on disabling the :confirmable option. This is my user.rb file:

```
class User < ActiveRecord::Base
devise :database_authenticatable, :recoverable,
:trackable, :validatable, :registerable,
:omniauthable
include DeviseTokenAuth::Concerns::User
end
```

And when registering a user I get the error:

```
ActionView::Template::Error (Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true):

You can confirm your account email through the link below:

<%= link_to 'Confirm my account', confirmation_url(@resource, confirmation_token: @token, config: message['client-config'].to_s, redirect_url: message['redirect-url']) %>

Any idea why?
Thanks,
Uri

Start with the User model configuration shown in user.rb and trace registration into the confirmation email template included in the error. Check why the disabled :confirmable configuration still reaches confirmation_url, then reproduce registration to verify it no longer attempts confirmation delivery or raises the missing-host error.
