Fixes the import empty folder problem. Once user import empty folder, the screen will back to labelling tool screen. Nothing new image will add and wont have message pop up. Able work on my laptop.

need to remove the println command which is suppose for debugging @toh-sie-hung
else in the long run the command prompt output will have random messages.

[toh-sie-hung]

sorry, forget to remove it. Thx for checking

[codenamewei]

these operation happens in ImageHandler.processFolder(projectID, rootFolder); too

running it two times will cause the running time to massively increase, recommend to keep this file as how it was

Advise changing in ImageHandler.java L 258

if(filesCollection.isEmpty())
        {
            loader.reset(FileSystemStatus.WINDOW_CLOSE_DATABASE_NOT_UPDATED);
            return;
        }

I just moved the code from toolfolderselector file to imagehandle file

[codenamewei]

Works well now.
