title: Jackson deserialize JsonIdentityReference (alwaysAsId = true)
body: <p>Following up on this question: <a href="https://stackoverflow.com/questions/12096216/jackson-serialize-deserialize-property-as-json-value">Question here</a></p>
  
  <p><code>@JsonIdentityReference(alwaysAsId = true)</code> and 
  <code>@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class)</code> works great from the Serialization end, but not so well when it comes time to deserialize since it can't resolve the Object ID reference.</p>
  
  <p>Is there a way to get this to deserialize?  Writing a custom deserializer seems like overkill.</p>
