Issue: KeyError in new pseudo-release extraction path

Beets is crashing currently when running mbsync on the whole library as well as attempting imports on some albums. It seems to be a problem that was introduced with #4714 with the assumption that res['release'] will be a dict contatining a 'status' key.. This has rendered beets unusable, so I would say is fairly high priority.

### Problem

Running this command in verbose (`-vv`) mode:

```
beet -vv import /downloads/ --from-scratch -t
