Napari saving training data shows done before actually done

[matham]

Describe the bug

In Napari, when curating data, when you click "save training data" to start exporting the cubes a popup pops up right away saying "done". Even though it only actually started saving the data.

This is very confusing because it takes a second for the progress bar to start going so I thought it was actually done right away. But the folder was still empty so I deleted it and got errors of course because it was still saving.

To Reproduce Hit save training data and you'll see the popup appear.

Expected behaviour For there to be no popup or to show it after it's actually done exporting all files.
