Autotag increments filename when set to no

When importing an album that already exists, beets seems to increment and add `.1` to the filename. Is it supposed to do that even when incremential is turned off? This only happens if i set `autotag` to `no`. If set to yes it works as expected.

I have one big folder with all my music (`/mnt/Music/Library/`) and then i have Lidarr add music to that folder.

### Problem

```sh
$ beet -vv import /mnt/Music/Library/YELLOW\ MAGIC\ ORCHESTRA/YMO/

### Setup

* OS: Debian 11.6
* Python version: 3.9.2
* beets version: 1.6.0
* Turning off plugins made problem go away (yes/no): no

My configuration (output of `beet config`) is:

```yaml
library: ~/.config/beets/library.db
directory: /mnt/Music/Library

paths:
default: $albumartist/$album/$track $title
singleton: $artist/Non-Album/$title
albumtype:soundtrack: Soundtracks/$album/$track $title
comp: Compilations/$album/$track $title

original_date: yes
per_disc_numbering: yes
threaded: yes
asciify_path: yes
clutter: [
.DS_Store,
Thumbs.DB
]

plugins: [
duplicates,
spotify
]

import:
copy: yes
write: yes
move: yes
group_albums: no
default_action: skip
duplicate_action: skip
quiet_fallback: skip
log: ~/.config/beets/import.log
incremental: no
incremental_skip_later: no
detail: no
timid: no
autotag: no
```

Start with the beet import command and reproduce the two consecutive imports using the verbose output and paths shown. Compare behavior when autotag is set to no versus yes, with incremential disabled. Done means the second import does not create .1 filename copies when that setting is off, with the existing import behavior still covered.
