Fixed S3 function result handling and updated default for s3_skip_empty_files setting

Fixed case when s3/s3Cluster functions could return incomplete result or throw an exception. It involved using glob pattern in s3 uri (like pattern/*) and an empty object should exist with the key pattern/ (such objects automatically created by S3 Console). Also default value for setting s3_skip_empty_files changed from false to true by default. #71947 (Nikita Taranov).
