When XWiki is initialized via a XMLRPC request, it is in a wrong state and redirect-to-login URLs will be wrong

To reproduce, start a wiki, then hit a XMLRPC URL locally (http://localhost/xwiki/xmlrpc/confluence) this will trigger the wiki initialization. Then try to hit a page in edit mode (without having an active session) though an external URL ( mywikiurl/xwiki/bin/edit/Main/WebHome). The redirection to the login will be wrong, and will point to http://mywikirul/xwikihttp://localhost/xwiki/bin/login/XWiki/XWikiLogin?srid=Y7gt4Ua1
