Setting parent_id doesn't move existing log searches

[gray-host]

My team is considering managing our SumoLogic enviornment using Terraform and I noticed this issue when importing some existing resources.

Steps to recreate:

1. terraform import an existing log search that exists within a subfolder of a larger folder
2. change the terraform resource definition to match existing configuration
3. apply so that plan shows no difference
4. change the parent_id argument to the folder containing the subfolder the search is already contained in
5. apply
6. the search will still be in the subfolder as shown by terraform plan detailing changes to be made
