test(cli): make copyto path assertions Windows-portable

The Windows SQLite unit job failed because two new copyto tests asserted on
raw POSIX dest strings. On Windows `str(Path("/tmp/research"))` renders with
backslashes, so the copyto dest is `\tmp\research/notes/...` (rclone accepts the
mixed separators — the product is fine). Compare the local dest via `Path(...)`
like the other tests, which normalizes separators cross-platform.
