Description

Currently I can't use ignorePaths init param with WicketServlet (but using WicketFilter works fine).

WicketServlet.goGet() and WicketServlet.doPost() call WicketFilter.processRequest(ServletRequest, ServletResponse, FilterChain) without passing FilterChain object, so WicketFilter.processRequest(..) throws NullPointerException.

We should omit chain.doFilter(..) if given FilterChain is null.
