Can't see the episode list of a podcast as an anonymous user, with anonymous access enabled

Steps to reproduce

1. Visit the podcasts page at https://baleafunk.eus/library/podcasts/ as an anonymous user. The pod has anonymous access enabled.
2. Click on a podcast to see the episode list.

What happens?

The user is asked to login. They can't see the episode list.

What is expected?

Our pod has anonymous access enabled, so the user should be able to see the episode list without logging in. In previous versions of Funkwhale that was the behaviour (we updated from 1.2.8 to 1.3.0)

Context

Funkwhale version(s) affected: 1.3.0

• Tested with Firefox and Chrome.
• Docker installation with nginx as reverse proxy.
• I can reproduce the bug in another two pods that use Funkwhale 1.3.0 and have anonymous access enabled: https://funk.firobe.fr/library/podcasts/ and https://mizik.o-k-i.net/library/podcasts/
