role:duplicty: Files in divided folder won't be backed up by duba

[bzblf]

files located directly in a folder (which is divided in duba via /etc/duba/duba.json with the entry "divide": true,) are not backed up

Example:
The folder parentfolder1contains folders and files. The folders and files in folder1, folder2 etc. will be found in the backup, but not the files that are directly in the folder parentfolder1.
In the listed Example below, the file file1.tar.gz will be missed in the backup.

[hostname Rocky8 ~]$ ll /parentfolder1
