In most of Python libraries like boto3, when listing contents of a bucket, an empty string as delimiter is considered as not provided (see for instance Apache Airflow). Also when using the boto3 library this 2 calls are semantically equivalent and return all keys under the bucket:
But in S3Mock whenever you provide a string, it becomes Some("") as the delimiter and returns nothing. Since it doesn't make much sense to have an empty string as delimiter, I've created this PR to transform that into None in order to be able to interoperate with popular Python frameworks that hardcode the "" into the call.
