B2 - 'Show files in subfolders' dosen't update images

[Jaff]

To reproduce this follow the steps below:

- try clearing image cache
- move in a folder with some subfolders containing images
- select Show files in subfolders from menu
- view one of subfolders/options - browser - thumbnails - cache

all subfolders aren't in cache even if all images are processed for thumbs in main folder with Show files in subfolders

To make all cache ok select from menu Rebuild thumbnails while still viewing all images from all subfolders
