[BUGFIX] OpenId needs library after removing classFile

After removing the classFile setting for services the OpenID
authentication service needs to have its library loaded
explicitly. Unlike the rest of the core this external
library doesn't use namespaces and can't rely on the autoloader.
Furthermore, the library might not have a unique name if
for example a second extensions delivers the same library,
therefor the problem is for now not solved with an ext_autoload
entry, but is required directly at where needed.
