pac4j: logout doesn't work with MongoSessionStore

[silentcharacter]

Hi Edgar!
I've tried using session(MongoSessionStore.class) and noticed that logout doesn't work.
Found out that session.unset() is not applied in mongo session collection. During next request unset parameter exists again.

Think there is a bug here with unset but for logout you should use destroy

@jknack I'm using jooby-pac4j\1.1.0\jooby-pac4j-1.1.0.jar!\org\jooby\internal\pac4j\AuthLogout.class
...
Optional profileId = ((Session)ifSession.get()).unset(Auth.ID).toOptional();
