The rclone backend wrote each object straight to its key, so killing an
upload to a local or sftp remote left a truncated object there that the
next backup trusted.
On every remote with a server-side move, an object is now written under
a name ending in `.partial` and moved onto its key with rclone's
operations.Move, which removes an object already at the key first;
drive, dropbox and others will not move onto one. Listings skip
`.partial` names. Rclone's own copy also requires the PartialUploads
flag; this does not, because hdfs shows a file while it is written
without setting it. Remotes without a move are written in place.
