Napari saving training data shows done before actually done #548
Description
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.
