title: Rails Sidekiq Mailer Job Url Helpers issue
body: <p>Using Rails 6 with Active Job (Sidekiq backend) whenever I try to send a mail (deliver_later) with a link_to I get the following error:</p>
  
  <pre><code>An ActionView::Template::Error occurred in background at 2019-11-25 17:18=
  :11 -0300 :
  
    Missing host to link to! Please provide the :host parameter, set defaul=
  t_url_options[:host], or set :only_path to true
  </code></pre>
  
  <p>I'm searching for days and found diferent solutions here in SO, but most of then are outdated and don't work anymore for rails 5+ .  What I tried so far (in development.rb):</p>
  
  <blockquote>
  <pre><code>&gt; Rails.application.routes.default_url_options[:host] = "https://myhost.com"
  &gt; 
  &gt; 
  &gt; config.action_mailer.default_url_options = { :host =&gt; https://"myhost.com" }
  &gt;   
  &gt; 
  &gt; config.default_url_options = { :host =&gt; https://"myhost.com" }
  &gt;      
  </code></pre>
  </blockquote>
  
  <p>None of then seems to work. Is there any more aproches to this? </p>
  
  <p>EDIT:</p>
  
  <p>In my mailer/view I'm trying to use the link_to like this:</p>
  
  <pre><code>&lt;p style="margin-bottom:25px;"&gt;Para redefinir tua senha, &lt;%= link_to "CLIQUE AQUI", reset_password_registration_url(token: @token) %&gt;&lt;/p&gt;
  </code></pre>
