All seasons are processed now, but those without any episodes are filtered out again as unavailable.
This fixes in issue where jellyfin reports all seasons as virtual
Reverted #450 which addressed the issue where the automatic grouping enabled libraries were not
functioning correctly. The previous fix inadvertently caused a bug for Jellyfin LDAP users,
preventing library syncing with a 401 error. Reverting this change temporarily until support for
automatic library grouping can be re-implemented
fix#489
Jellyfin allows combined episodes, like `S01E01-E02`,
but seasons containing such episodes are only recognized
as `Partially Available`. This commit should fix that.
