"Recent" columns on front page no longer display any results

Steps to reproduce

What is expected?

Results should be returned for each

Context

Funkwhale version(s) affected: 0.20.0+git.668615a8

• Browser: Firefox, Chrome
• Instance Configuration: Docker multi-container, Nginx

Taking Favorites as an example, this is the call sent out when trying to pull back recent favorites:

GET https://<URL>/api/v1/favorites/tracks/?scope=user&ordering=-creation_date&page_size=5

The response is:

{"count":0,"next":null,"previous":null,"results":[]}

Removing the scope=user from the GET request brings back the correct number.

Probably caused by changes made in 668615a8
