OCC does not see S3 directory when created via AWS CLI

Steps to reproduce

1. Install AWS CLI for python:
   pip install awscli
2. Configure AWS CLI
   aws configure
3. Create temp dir and copy it to s3
   mkdir /tmp/test ; echo 123 > /tmp/test/1
   aws s3 cp /tmp/test s3:///test --recursive
4. Run OCC
   sudo -u php-fpm occ files:scan --path=/admin/files/AmazonS3/ -vvv

Expected behaviour

OCC should return all directories in bucket

Actual behaviour

When using aws cli to copy directory to s3 bucket, OCC does not see it while using files:scan.
However when I access AWS CONSOLE (website), create directory and upload files - OCC can see it.
