CVE-2011-1088

Complete the fix for this issue. The optimisation not to configure an authenticator of there were no security constraints meant that in that case @ServletSecurity annotations had no effect. The unit tests did not pick this up since they added an authenticator directly.
Add an explicit unit test for this scenario.
