Duplicated entries in the Roles dropdown when creating a new Config Context

[cmsirbu]

Environment

• Nautobot version (Docker tag too if applicable): 2.1.7 https://demo.nautobot.com/
• Python version:
• Database platform, version:
• Middleware(s):

Steps to Reproduce

1. Create a new Config Context
2. In the Assignment panel, click the Roles field
3. Observe duplicated role entries (distribution, edge, Backbone etc. all appear twice).

Expected Behavior

Each role should only appear once.

Observed Behavior

Investigation

This API call sent on click is the one returning the duplicated objects: https://demo.nautobot.com/api/extras/roles/?q=&limit=50&offset=0&depth=0&content_types=dcim.device&content_types=virtualization.virtualmachine

It looks like the duplication comes from content_types=dcim.device&content_types=virtualization.virtualmachine, if you remove one of them then roles appear only once in the result.
