Imported `aws_cognito_user_pool` with no tags causes update in plan

[gdavison]

When importing a aws_cognito_user_pool with no tags into Terraform, a diff is generated in the plan. It doesn't force a change, but does show up if there are other changes.

The import operation is storing an empty map of tags, but the plan wants to update it to nil:

- tags = {} -> null
