Horizon cannot delete buckets with prefix PRE/

Steps:

Using an cli to upload files to a S3 Container on openstack swift using the following command:

 aws --endpoint http://url s3 cp file s3://mybucket//file

The Swift will assume the file has a prefix '/' and will list it as PRE/:

aws --endpoint http://url s3 ls s3://mybucket/

                           PRE /

This file can be delete through cli using a path like s3://mybucket//file.

On Horizon, if will list a folder with no name on the table and will not delete.
