Steps to Reproduce

Summary:
I observed the issue on a CustomValidation script. When I try to get the tag from a DeviceRole, it is everytime dcim.DeviceRole.None.

Exect Steps:

Create a Tag
Create a DeviceRole and assign the tag to it
Creating a CustomValidation Script for Devices and enable it in NetBox

from extras.validators import CustomValidator
from dcim.models import DeviceRole

class MyCustomValidator(CustomValidator):
    def validate(self, instance, request):
        fullDeviceRole = DeviceRole.objects.get(slug=instance.role.slug)
        self.fail(fullDeviceRole.tags) # Just for debugging purposes

Try create a Device with your created Device Role
You will get a failing message with dcim.DeviceRole.None instead of your tag name

Expected Behavior

Getting name of the tag.

Observed Behavior

Getting dcim.DeviceRole.None
