.well-known/openid-configuration should return endpoints as primary URL

Steps to reproduce:

1. Install and setup two OpenAM 11.0.0 servers in site, behind a load balancer.
   Load balancer : https://lb.example.com/openam/
   OpenAM 1 : http://openam01.example.com:8080/openam/
   OpenAM 2 : http://openam02.example.com:8080/openam/
2. Log in to OpenAM and create an OAuth 2.0 provider.
3. Access to https://lb.example.com/openam/.well-known/openid-configuration .
   -> Every endpoint is not shown as the primary URL.
