fix: catch new type error being thrown

[jvillafanez]

This is a new error that is thrown due to the update to php 8.3

Description

The copyKeys method isn't part of the interface and isn't likely available in most of the storages. It relies on the encryption wrapper (

core/lib/private/Files/Storage/Wrapper/Encryption.php

Line 1108 in 04fbcb0

protected function copyKeys($source, $target) {

) to stop the call from reaching the storage.

Related Issue

Found in owncloud/encryption#418 . Further details in that PR.

Motivation and Context

This is a quick and dirty solution to restore the previous behavior (from php 7.4) to make the tests from owncloud/encryption#418 pass
