--fields=sync state not working with box folder: get

[TonyHuckle]

when running 'box folders:get --as-user= --fields=sync_state'

only the type and ID fields are returned.

expected sync_state which is returned when doing the following in postman

curl -X GET
'https://api.box.com/2.0/folders/?fields=sync_state'
-H 'Authorization: Bearer <>'
-H 'Postman-Token: <>'
-H 'cache-control: no-cache'

I get the result

{
"type": "folder",
"id": "<>",
"etag": "2",
"sync_state": "synced"
}
