nielash 998df26ceb onedrive: fix --metadata-mapper called twice if writing permissions 
Before this change, the --metadata-mapper was called twice if an object was
uploaded via multipart upload with --metadata and --onedrive-metadata-permissions
"write" or "read,write". This change fixes the issue.

**However** the delta listing API **only** works at the root of the

and discards all the data that is not under the directory you asked
for. So it will be correct but may not be very efficient.
This is why this flag is not set as the default.
As a rule of thumb if nearly all of your data is under rclone's root
directory (the |root/directory| in |onedrive:root/directory|) then
using this flag will be be a big performance win. If your data is
mostly not under the root then using this flag will be a big
performance loss.
It is recommended if you are mounting your onedrive at the root

* - https://{Endpoint}/drives/{driveID}/items/children('{leaf}')/{route}
* - however, this API does NOT support multi-level leaf like a/b/c
* - https://{Endpoint}/drives/{driveID}/items/children('@a1')/{route}?@a1=URLEncode("'{leaf}'")
