cubicweb #4655613 __default_empty_db__ can be built with non-default ApptestConfiguration [open]

eg. if web/test/unittest_web.py is executed first, the cached default database is built with CubicWebServerConfig as configcls. This config cls redefine the default base url, so created entities have a different cwuri than the default "http://testing.fr/cubicweb". This make web/test/unittest_view_xmlrss.py fails.

The default database should always be created with default configcls.
