In release 1.0.4, I can no longer create a fifo queue by setting the attribute FifoQueue=true.

I believe it is due to this code from this issue: https://github.com/localstack/localstack/pull/6117/files

FifoQueue was set as an internal attribute which cannot be changed: 

(snip from PR)
INTERNAL_QUEUE_ATTRIBUTES = [
    # these attributes cannot be changed by set_queue_attributes and should
    # therefore be ignored when comparing queue attributes for create_queue
    QueueAttributeName.ApproximateNumberOfMessages,
    QueueAttributeName.ApproximateNumberOfMessagesDelayed,
    QueueAttributeName.ApproximateNumberOfMessagesNotVisible,
    QueueAttributeName.ContentBasedDeduplication,
    QueueAttributeName.CreatedTimestamp,
    **QueueAttributeName.FifoQueue,**
    QueueAttributeName.LastModifiedTimestamp,
    QueueAttributeName.QueueArn,
]

Now I see this error when attempting to create a fifo queue with the java sdk. This worked last week fine, no changes other than pulling the latest localstack image.

nested exception is com.amazonaws.services.sqs.model.InvalidAttributeNameException: Unknown Attribute FifoQueue.
