title: Extra quotes being added to @Query
body: <p>I have the following JSON structure:</p>
  
  <pre><code>{
    "communication": {
        "office": {
          "email": "test@example.com"
        },
        "private": {
          "email": "test2@example.com"
        },
    }
  }
  </code></pre>
  
  <p>I want to query dynamically for the email based on the type e.g. office or private. When I use the following command:</p>
  
  <pre><code>@Query(value = "{ 'communication.?0.email' : ?1 }")
  Object findByEmail(String type, String email);
  </code></pre>
  
  <p>The </p>
  
  <pre><code>'communication.?0.email'
  </code></pre>
  
  <p>is converted to</p>
  
  <pre><code>'communication."office".email'
  </code></pre>
  
  <p>and mongo didn't find an entry. How can I avoid the quotes before and after office?</p>
