No pipeline connections with for stream

After upgrading from Graylog 6.0 -> 6.1 I'm seeing a lot of 404 errors with links like:
https://graylog/graylog/api/streams/666307999dd86620248c4509/pipelines

The response:
```
type: ApiError
message: No pipeline connections with for stream 666307999dd86620248c4509
```

Checking another graylog 6.0 instance I don't see any of these.
