PipeCLI: fix for restored files listing

[ekazachkova]

pipe storage ls s3://<bucket-name>/ shall be able to list restored files. The following issues were discovered:

• currently, pipe shows restored files with --recursive option only
• pipe storage ls s3://<bucket-name>/<restored file path> does not show restored file via full cloud path
• pipe storage ls s3://<bucket-name>/<restored file path> does not show single-restored files (those files that have type = FILE )

This PR brings fixes for issues above.
