We should display something more informative to the user here.

At the very least, we should replace Copying recording first... with Copying recording (this may take a while if Spacy dependencies need to be downloaded on the first run)...

To Reproduce

In a fresh clone, first create a recording, then attempt to scrub it in the dashboard:

python -m openadapt.app.dashboard.run
