fix(propagateuploadng): do not encode davUrl

sabre/dav does not seem to approve of percent-encoded base URLs (e.g.
`http%3A//nextcloud.local/...`), it will then consider them as absolute
paths and fail.

--> adapt fix from #9334 to only encode the remote path, as sabre parses
those paths just fine.

Resolves: #9582
