title: Missing fields when unwrapping a Parcel object with Parceler library
body: <p>I have a Java Bean class, annotated with <code>@Parcel(Parcel.Serialization.BEAN)</code> and Gson's <code>@SerializedName</code> on some fields:</p>
  
  <p><strong>Question.java:</strong></p>
  
  <pre><code>@Parcel(Parcel.Serialization.BEAN)
  public class Question {
  
      private Integer id;
      private String title;
      private String description;
      private User user;
  
      @SerializedName("other_model_id")
      private Integer otherModelId,
  
      @SerializedName("created_at")
      private Date createdAt;
  
      // ----- Getters and setters -----
  }
  </code></pre>
  
  <p>When I'm starting <code>ShowQuestionActivity</code>, I pass my Parceled <code>question</code> object to it (where <code>question</code> has all fields set):</p>
  
  <pre><code>Intent intent = new Intent(context, ShowQuestionActivity.class);
  intent.putExtra("extra_question", Parcels.wrap(question));
  startActivity(intent);
  </code></pre>
  
  <p>On <code>ShowQuestionActivity</code>, I get "extra_question" from my <code>intent</code> object:</p>
  
  <pre><code>Question question = Parcels.unwrap(intent.getParcelableExtra(Constants.EXTRA_QUESTION));
  </code></pre>
  
  <p>But Parceler returns me only title and description (Strings)... All other fields are <strong>null</strong>.  </p>
  
  <p>Wrapping the object with <code>Parcels.wrap(question)</code> and unwrapping it with <code>Parcels.unwrap(question)</code> on debugger works perfectly, but after passing it through intent, it seems to "lose" its values, but I can't find the problem...</p>

  <p>My Parceler setup is the following:</p>
  
  <p>Module <strong>build.gradle</strong>:</p>
  
  <pre><code>dependencies {
      compile 'org.parceler:parceler-api:1.1.4'
      apt 'org.parceler:parceler:1.1.4'
  }
  </code></pre>
  
  <p>And in my project's <strong>build.gradle</strong>:</p>
  
  <pre><code>dependencies {
      classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
  }
  </code></pre>
