In OidcCookieTokenStore#logout, there's an unnecessary null check here:

https://github.com/wildfly-security/wildfly-elytron/blob/1.x/http/oidc/src/main/java/org/wildfly/security/http/oidc/OidcCookieTokenStore.java#L140

Notice that when we get to this point, it's not possible for securityContext to be null. Thus we can remove the null check on line 140.
