getRequestFileStatus considers done files that are in canceled request

TLDR: if a Request is canceled when having replicated everything and registered nothing, it ends up being `Processed` in the TS

```python
In [2]: ReqClient().getRequestStatus(54974805)
Out[2]:
{'OK': True,
'Value': 'Canceled',
'rpcStub': (('RequestManagement/ReqManager',
{'timeout': 600, 'useAccessToken': False}),
'getRequestStatus',
[54974805])}

# This is wrong !!!

[buggyReq.json](https://github.com/user-attachments/files/21147543/buggyReq.json)

Out[3]:
