Make storage deletion work on more S3 providers, don't use access URL…

… for deletion (#1600)

I came across [this
problem](https://forum.webrecorder.net/t/deleting-crawl-failure/512) and
noticed that the access URL is used when deleting files, causing my file
deletions to fail on OpenStack SWIFT S3 (relates to #1090). This trivial
change makes it work there.
