double slash in Conversation test urls break redirect

The Conversation tests all call AbstractConversationTest.getPath() with strings starting with / such as /storm.jspx. Since the method tacks a / at the end of the context root you end up with urls for the form foo//bar.jsf. While tomcat appears to think that this is the same url as foo/bar.jsf, jetty doesn't. This breaks the redirect in LongRunningConversationPropagatedByFacesContextTest.testConversationPropagatedOverRedirect.

Removing the / from the arguments to getPath fixes the problem.
