Bug: trsync crashes with "UnexpectedError"

Hi,

I ran trsync v0.2.1 "manually" with the following command:

```
trsync ~/Tracim/spacename/ tracim.mydomain.fr 9999 myusername
```

And it immediately crashed with the following error:

```
[2024-10-03T20:53:16Z INFO trsync::operation::operator] Proceed event : Remote(Created(ContentId(1520)))
[2024-10-03T20:53:16Z ERROR trsync::run2] Operate error : Operator error: Missing parent error: Unable to operate on following changes (missing parents): ☁🆕 some-dir/some-file.txt
Error: UnexpectedError("Operator error: Missing parent error: Unable to operate on following changes (missing parents): ☁🆕 some-dir/some-file.txt: Missing parent
error: Unable to operate on following changes (missing parents): ☁🆕 some-dir/some-file.txt")
```

On the server side, looking at the apache logs, it matches the following logs:
```
XX.XX.XX.XX - - [03/Oct/2024:20:53:14 +0000] "GET /api/auth/whoami HTTP/1.1" 200 5189 "-" "-"

```

What I think I did:

1. synchronize this file with trysnc 0.2.0
2. stopped trync
3. deleted the file on my computer
4. ran trsync 0.2.1 (the above error and logs)

Do not hesitate to tell me if I can provide more information.

Thanks,
Yvan
