Role Icons not displaying on Party/Raid Frames in Classic SoD

[skywardpixel]

Troubleshooting Steps

Role icons don't show in party/raid frames.

No role icon option is available in ElvUI Unit Frame settings

Attempted to fix locally with the changes in #1485 and it seemed to work.

Describe the expected behavior and what actually happened?

Since SoD supports roles, I expect role icons to show in Party/Raid Frames as they would in Cataclysm Classic.

Reproducing the issue.

Get into a party/raid. No role icon is shown.

Open ElvUI Config /ec and go to unit frame settings. No "Role Icon" settings is available.
