title: Angular4 component dies, lifecycle hooks not firing after navigating from and then back
body: <p>What could go wrong, if the component lifecycle events are not fired (except <code>ngOnDestroy</code>) on second and onward activation of the component? I made a simplified test case with very similar setup: <a href="http://plnkr.co/edit/0CTtzFbaJPHYRvhzogtS?p=preview" rel="nofollow noreferrer">http://plnkr.co/edit/0CTtzFbaJPHYRvhzogtS?p=preview</a> and that works...
  But not my real code. I can see only these events:</p>
  
  <p><a href="https://i.stack.imgur.com/OVLSY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/OVLSY.png" alt="enter image description here"></a></p>
  
  <p>In the later cases the content is not correctly rendered either: it is rendered only what's before the first binding. But there is no any error message or warning during compilation or in the browser console.</p>
  
  <p>The major difference between the setup from above and the original code is that tha later is webpacked.</p>
  
  <p>Any idea? Thank you!</p>
