Description

Since WICKET-6360 some tests in Wicket Native WebSocket (and also at Wicket Spring Boot Starter) were failing with NullPointerException because MockServletContext#getEffectiveSessionTrackingModes() is returning null.

It would be better if org.apache.wicket.protocol.http.mock.MockServletContext#getEffectiveSessionTrackingModes() returns a set with cookie mode, because cookie is the most close to real life applications.
