Deleting user while the user is logged in results in NPE when user tries to access his profile

Steps to reproduce:

1. setup crowd authentication
2. add a user to crowd
3. log in to FE+CRU as that user
4. while the user is logged in, delete the user in the admin panel

You get the 500 Server Error and the following NPE:
