posix: file revisions are not deleted when item is purged from trash

[butonic]

create a new file and make three edits to it. The disk should now know them:

❯ tree -ah /home/jfd/.opencloud/storage/users/users/
[4.0K]  /home/jfd/.opencloud/storage/users/users/
└── [4.0K]  cd88bf9a-dd7f-11ef-a609-7f78deb2345f

9 directories, 4 files

when you delete the file it is moved to the trash and the disk will look like this:

❯ tree -ah /home/jfd/.opencloud/storage/users/users/
[4.0K]  /home/jfd/.opencloud/storage/users/users/
└── [4.0K]  cd88bf9a-dd7f-11ef-a609-7f78deb2345f
    ├── [4.0K]  .oc-nodes

    │   │           └── [4.0K]  e2

12 directories, 5 files

now if you purge the item from trash the node metadata for revisions should have been deleted. however, we can see that they are still there:
