# Detailed description

When I try to list stacks and filter the stack status, it lists all the stacks rather than filter them out.

I saw someone had this issue before and was meant to be fixed, but doesnt seem like its fixed:
- https://github.com/localstack/localstack/issues/2698

## Expected behavior

Stacks should be filtered


## Actual behavior

All stacks are returned

# Steps to reproduce

Run latest docker version of localstack.
Create new stack
Try to run something like:
aws --endpoint-url=http://localhost:4566 cloudformation list-stacks --stack-status-filter DELETE_FAILED

It will return all stacks when it should return an empty list

## Command used to start LocalStack
docker run --network host -d -e DEFAULT_REGION="eu-west-1" localstack/localstack:latest

## Client code (AWS SDK code snippet, or sequence of "awslocal" commands)
aws --endpoint-url=http://localhost:4566 cloudformation list-stacks --stack-status-filter DELETE_FAILED

Using boto3, the same thing happens:
response = self.__cloudformation_client.list_stacks(StackStatusFilter=['CREATE_FAILED'])

...

state = CloudFormationRegion.get()
    set_name = req_params.get('StackSetName')
    stack_set = [sset for sset in state.stack_sets.values() if sset.stack_set_name == set_name]
    if not stack_set:
        return not_found_error('Stack set named "%s" does not exist' % set_name)
    stack_set = stack_set[0]
    op_id = req_params.get('OperationId') or short_uid()
    sset_meta = stack_set.metadata
    accounts = extract_url_encoded_param_list(req_params, 'Accounts.member.%s')
    accounts = accounts or extract_url_encoded_param_list(req_params, 'DeploymentTargets.Accounts.member.%s')
    regions = extract_url_encoded_param_list(req_params, 'Regions.member.%s')
    stacks_to_await = []
    for account in accounts:
        for region in regions:
            
            LOG.debug('Deploying instance for stack set "%s" in region "%s"' % (set_name, region))
            cf_client = aws_stack.connect_to_service('cloudformation', region_name=region)
            kwargs = select_attributes(sset_meta, 'TemplateBody') or select_attributes(sset_meta, 'TemplateURL')
            stack_name = 'sset-%s-%s' % (set_name, account)
            result = cf_client.create_stack(StackName=stack_name, **kwargs)
            stacks_to_await.append((stack_name, region))
            
            instance = {
