Remove - Delete all files does not delete Logs/VBoxUI.log => Fixed in SVN

[a587730]

It is simple yet annoying problem. 'Delete all files' is expected to delete all files created by virtualbox including configurations, linked virtual hdds, and logs. But since 6.1, It does not delete Logs/VBoxUI.log in VM directory and prevents me to re-create a new VM with the same name unless I delete it manually.
