Bug: trsync_manager crashes when doing a permanent delete

Hi,

When I do a "permanent delete" (introduced in Tracim 4.9.0) from the web interface, `trsync_manager` crashes with the following messages:

```
[2024-10-17T20:24:33Z INFO trsync::remote::watcher] remote event : content.deleted.html-document (14642)
[2024-10-17T20:24:33Z INFO trsync::run2] Proceed event Remote(Deleted(ContentId(14642)))
[2024-10-17T20:24:33Z INFO trsync::remote::watcher] remote event : content.deleted.html-document (14642)

[2024-10-17T20:24:33Z INFO trsync::run2] [my.tracim.fr::682] Set activity to Erreur
```

To be precise, It does not really crashes (because the process stays running), but it can not sync anything until being restarted.

It does not happen when I do a "classical delete" from the web interface:
