Set "manage_default_resource_id" during import of default resources

This fixes an issue where importing a default resource will leave
the manage_default_resource_id empty in the state file. Any change
in the TF config would force an unwanted delete/recreate.

Fix this by setting the manage_default_resource_id on import.
