Steps to reproduce

NextCloud file encryption is enabled, add an S3 bucket to the external storage and set it to not be encrypted
Upload some files to external storage via WebDAV
Modify these uploaded files and re-upload via WebDAV
There is no problem with the updated file, but two messages will be seen in the NextCloud log: OC\ServerNotAvailableException: Legacy cipher is no longer supported! / Couldn't re-calculate unencrypted size for files_versions

Expected behaviour

The version file should be correctly identified as an unencrypted file.

Actual behaviour

NextCloud seems to think this is an encrypted file and tells the user that Legacy cipher is no longer supported.
