title: How to use with_permissions_to in declarative_authorization?
body: <p>I have the next model:</p>
  
  <pre><code>class AssignmentReport &lt; ActiveRecord::Base
  
  end
  </code></pre>
  
  <p>And 2 permissions defined to manage it:</p>
  
  <pre><code>privilege: :approve_all, context: :assignment_reports
  </code></pre>
  
  <p>AND</p>
  
  <pre><code>privilege: :approve_some, context: :assignment_reports
  </code></pre>
  
  <p>When I try in the console:</p>
  
  <pre><code>AssignmentReport.with_permissions_to(:approve_all, user: user)
  </code></pre>
  
  <p>It returns nothing (empty) and I expect it to return 2 records.</p>
  
  <p>What am I doing wrong?</p>
