Subject: [PATCH] idp/proxy: Match users by ID instead of name by default

Reconfigure the oidc clients for lico, so that lico adds the "lg.uuid" to
tokens and userinfo by default. That claim will contain the userid. So
we can now use the userid for matching users when using the default
idm/idp configuration. This fixes further problems so that users being
recreated with the same name are correctly treated as differnt users.

Fixes: #904
