title: kaminari page_entires_info error with I18n.locale
body: <p>I use <a href="https://github.com/amatsuda/kaminari" rel="nofollow">https://github.com/amatsuda/kaminari</a> for pagination on my rails projects.</p>
  
  <p>On this page <a href="https://github.com/amatsuda/kaminari/issues/257" rel="nofollow">https://github.com/amatsuda/kaminari/issues/257</a> show the issue with this helper.</p>
  
  <p>I have checked with adding to my gem file kaminari from master branch:</p>
  
  <pre><code>gem 'kaminari', :git =&gt; 'git://github.com/amatsuda/kaminari.git'
  </code></pre>
  
  <p>Also I have checked with last version <code>kaminari 0.14.1</code>, but it still does not translate to another language:</p>
  
  <p>I can see on my view the error:</p>
  
  <p><code>Display Entries</code> with <code>translation missing: es.helpers.page_entries_info.more_pages.display_entries</code></p>
  
  <p>I have added to my <code>es.yml</code> the next code:</p>
  
  <pre><code>helpers:
      page_entries_info:
        one_page:
          display_entries:
            zero: "Ningún %{entry_name} encontrado"
            one: "Mostrando &lt;b&gt;1&lt;/b&gt; %{entry_name}"
            other: "Mostrando &lt;b&gt;todos %{count}&lt;/b&gt; %{entry_name}"
        more_pages:
          display_entries: "Mostrando %{entry_name} &lt;b&gt;%{first}&amp;nbsp;-&amp;nbsp;%{last}&lt;/b&gt; de &lt;b&gt;%{total}&lt;/b&gt; en total"
    views:
      pagination:
        first: "&amp;laquo; Primero"
        last: "Último &amp;raquo;"
        previous: "&amp;lsaquo; Anterior"
        next: "Siguiente &amp;rsaquo;"
        truncate: "..."
  </code></pre>
  
  <p>The views first, last, previous...etc is working fine but the <code>page_entries_info:</code> helper is  not working fine.</p>
  
  <p><strong>if anyone has managed to solve this problem, would be nice if you share the solution. thanks</strong></p>
