title: Issue with Ignoring nested Properties using Automapper
body: <p>I have ran into an issue where I am trying to ignore properties within properties. e.g.</p>
  
  <pre><code>Mapper.CreateMap&lt;Node, NodeDto&gt;()
                  .ForMember(dest =&gt; dest.ChildNodes, opt =&gt; opt.Ignore())
                  .ForMember(dest =&gt; dest.NodeType.EntityType.Properties, opt =&gt; opt.Ignore());
  </code></pre>
  
  <p>I get following exception:</p>
  
  <pre><code>{"Expression 'dest =&gt; dest.NodeType.EntityType.Properties' must resolve to top-level member.\r\nParameter name: lambdaExpression"}
  </code></pre>
  
  <p>Any idea?</p>
