Clicking "Datalor" logo from "import dataset page" results in empty folder even though some have been downloaded

[kpu]

1. Run fresh opuscleaner
2. Load http://localhost:8000 and get the empty folder (expected)
3. Click import dataset, select Maltese and English, click way too many buttons to download everything.
4. Wait a bit for some to have downloaded
5. Click datalor logo which takes me back to the home page with the empty folder. I was expecting to see the data sets that had finished downloading, not an empty folder.
   Note that refreshing the home page works correctly.
