SAML new username issue

[makhoff]

Description:

Hello.
When I configured SAML with settings from this issue, new user created in format "Display Name, login" and I can't manage him from RocketChat console(only via REST API) .

In logs I see that parameter username received as "username":["XXX, YYY","TSTDMN\xxx.yyy"]" instead of ""username":["XXX, YYY"]"

Steps to reproduce:

1. Configure SAML with ADFS
2. Set "Generate Username" = false
3. Sign in with new SSO user

Expected behavior:

Got username in format ""username":["XXX, YYY"]"

Actual behavior:

Server Setup Information:

• Version of Rocket.Chat Server: 1.2.0
• Operating System: RHEL 7
• Deployment Method: on premise
• Number of Running Instances: 1
• DB Replicaset Oplog: Enabled
• NodeJS Version: 8.11.4
• MongoDB Version: 4.0.10
