Before this change we were only counting moves as checks. This means
that when using `rclone move` the `Transfers` stat did not count up
like it should do.
This changes introduces a new primitive operations.MoveTransfers which
counts moves as Transfers for use where that is appropriate, such as
rclone move/moveto. Otherwise moves are counted as checks and their
bytes are not accounted.
