If a form upload is configured to save files within
"1:/user_upload/test/" (saveToFileMount: '1:/user_upload/test/'),
an upload will be saved within
"1:/user_upload/test/form_<random>/file.png".
Lateron, the DeleteUploadsFinisher delete
"1:/user_upload/test/form_<random>/file.png".
If "1:/user_upload/test/form_<random>/" is emty, this folder will be
deleted too.
This patch prevents the DeleteUploadsFinisher from trying to delete the
top level upload folder "1:/user_upload/test/".
