orphan files/folders on harddrive

## Describe the bug

My instance uses much more storage on the disk than expected. When looking into what files use the space I found files on the disk that I have deleted in ocis e.g. `storage/users/spaces/00/7f0f4e-cb0c-4d60-a229-180920aa97ec/blobs/97/79/ab/b8/-bbea-4d25-bee8-d418129a5568`

The messagepack of that file has this content:
```
{
"user.ocis.blobid": "9779abb8-bbea-4d25-bee8-d418129a5568",
"user.ocis.blobsize": "10139136",
"user.ocis.cs.adler32": "\ufffdLwv",
"user.ocis.cs.md5": "\u0014\ufffd\ufffd{\ufffdĮH\ufffd@0\ufffdh\ufffd\ufffd\ufffd",
"user.ocis.cs.sha1": "\ufffd\ufffd\ufffd\u001f\u0015\ufffdENlJu\ufffd\ufffd\u001c˲Ssp\ufffd",
"user.ocis.name": "P1120390.JPG",
"user.ocis.parentid": "dbd28bd2-27fb-4f8c-92b7-40fa31753e37",
"user.ocis.type": "1"
}
```

I can find it's parent on disk:
```
ls ./storage/users/spaces/00/7f0f4e-cb0c-4d60-a229-180920aa97ec/nodes/db/d2/8b/d2/-27fb-4f8c-92b7-40fa31753e37 -lh

....
```

The parent has this messagepack content:
```
{
"user.ocis.name": "2022-04-18-22-Bandipur-Urlaub",
"user.ocis.parentid": "4629d530-c6f7-4fdf-ab4c-8ce3025a9d9c",
"user.ocis.propagation": "1",
"user.ocis.tmp.etag": "",
"user.ocis.tmtime": "2023-07-04T09:36:22.416708035Z",
"user.ocis.treesize": "951625660",
"user.ocis.type": "2"
}
```
These are files that I have deleted previously, including the folder.

I cannot find that folder or the files in the ocis webUI, nor the but not the grand-parent with the id `4629d530-c6f7-4fdf-ab4c-8ce3025a9d9c` anywhere on disk

## Steps to reproduce

Not sure! But I have uploaded a lot of files, generated previews (what sometimes crashed), deleted files, created & deleted spaces

## Expected behavior
no orphan files/folders on harddrive

## Actual behavior
orphan files/folders exist on the harddrive
