title: Carbon formatLocalized not working in Blade
body: <p>In a Blade view I have this code</p>
  
  <p><code>{{ \Carbon\Carbon::setLocale("es") }}
   {{ $registro-&gt;fecha_desde-&gt;format("l j F Y") }}&lt;br /&gt;
   {{ $registro-&gt;fecha_desde-&gt;formatLocalized("%A %d %B %Y") }}&lt;br /&gt;
   {{ $registro-&gt;fecha_desde-&gt;diffForHumans() }}</code></p>
  
  <p>This does not work, it returns:   </p>
  
  <pre><code>Friday 30 December 2016
  Friday 30 December 2016
  dentro de 1 semana 
  </code></pre>
  
  <p>So, format() and formatLocalized always returns the date in english format. 
  diffForHumans returns the date localized (in spanish in this case). </p>
  
  <p>Am I missing something? cant believe "Carbon's formatLocalized" is not returning localized formated dates....</p>
