Current OIDC plugin does not name new accounts properly

[mkosek]

As reported in the FreeIPA wiki OIDC registration ticket, when OIDC plugin cannot find issuer&subject pair in FreeIPA wiki database, it will create a new account. However, it will not set the right user name:

+---------+-----------+----------------+---------------+------------------+-------------------+----------------+----------------------------------+--------------------------+------------------+--------------------------+-------------------+-------------------+----------------+-----------------------+---------+---------------------------------------+
| user_id | user_name | user_real_name | user_password | user_newpassword | user_email | user_touched | user_token | user_email_authenticated | user_email_token | user_email_token_expires | user_registration | user_newpass_time | user_editcount | user_password_expires | subject | issuer |

I am specifically talking about the "User1" part. https://www.mediawiki.org/wiki/Extension:OpenID_Connect is talking about "preferred username was provided by the issuer", so I wonder if there is some Ipsilon/OIDC setting that could let the plugin use Fedora user name as the "preferred username".

Workaround: have new user renamed manually by some of the wiki admins until this is fixed (you can drop email to mkosek at redhat.com).

@mkosek Right, we hit this one too in staging, and this should have been fixed now. We didn't provide preferred_username before, but we do now.
