beet import --timid -A does not ask for confirmation

Following command imported and moved files despite the `--timid` flag :

```sh
$ beet -vv import --timid -A $sourcepath
```

Same command without `-A` led to confirmation dialog as expected.

```sh
$ beet version
beets version 2.6.1
Python version 3.13.5
plugins: discogs, edit, fetchart, info, mbsync, musicbrainz
```
