copy,move: restore --no-traverse flag

Browse Source 
The --no-traverse flag was not implemented when the new sync routines
(using the march package) was implemented.

This re-implements --no-traverse in march by trying to find a match
for each object with NewObject rather than from a directory listing.

### --no-traverse ###
The `--no-traverse` flag controls whether the destination file system
is traversed when using the `copy` or `move` commands.
`--no-traverse` is not compatible with `sync` and will be ignored if
you supply it with `sync`.
If you are only copying a small number of files (or are filtering most
of the files) and/or have a large number of files on the destination
then `--no-traverse` will stop rclone listing the destination and save
time.
However, if you are copying a large number of files, especially if you
are doing a copy where lots of the files under consideration haven't
changed and won't need copying then you shouldn't use `--no-traverse`.
See [rclone copy](/commands/rclone_copy/) for an example of how to use it.
