NullPointerException thrown when connecting to a just started XWiki.

When creating a new conenction to an XWiki that was just started, on the XWiki part a NullPointerException is being thrown because the XWiki Context not being initialized by the XML-RPC.

Even though a workaround exists for this by access pages trough the browser to init the context manually, this should be fixed, either using the workaround automatically and accessing a page like Main.WebHome, or changing server-side code so the context gets initialized properly.

From what I tested, at least from 1.5.1 and beyond, all the XWiki versions are affected.
