Broken logout from Web console when is used Elytron subsystem

When we use EAP with Elytron (standalone-elytron.xml configuration file) we aren't able to logout from Web console.

With legacy security realms everything is ok.

How to reproduce

• start EAP standalone.sh -c=standalone-elytron.xml
• log in to Web console on http://localhost:9990
• invoke logout
  You will get this url http://localhost:9990/logout
