Hello Team,

[Problem Description]

OIDC User Realm Role Mapper does not handle single value token claim correctly

[Steps to Reproduce] 

1) Create a new test OIDC client

2) Under Client > <My client> > Mappers , create a new mapper

The mapper type is User Realm Role, with the following settings as below

Claim Json Type is String

Multivalued is false

Add to ID token is false

Add to Access token is true

Add to user info is false

3) Create one role for the client and assign it to the user

4) Under Clients >Client Scopes > Evaluate

We would see :

"role_mapper_name": "[role_name]" 

The cu expects:

"role_mapper_name": "role_name"
