CBM s3 restore errors are printed twice

Build: 7.0.0-1902

Steps:

Create a bucket with 100 scopes and 1 collection in each scope (including default scope and collection)
Load 1000 items in each named scope (except default scope)
Configure backup with s3
Take backup of the bucket
Restore it to a bucket which has same scope names but with different id

Restore failures are printed twice:

`--map-data` option only works for the Data service. Will not restore the metadata for any other service
