Clear DB parameters do not delete Blob-directory

[handelaar2]

Describe the bug

The beacon clear-db parameters promise to delete the data directory:
--clear-db Prompt for clearing any previously stored data at the data directory.
--force-clear-db Clears any previously stored data at the data directory.
However after applying the above parameter, the number of blob-files remains unchanged.
The Blob-directory (=data) does not get cleared.

Has this worked before in a previous version?

🔬 Minimal Reproduction

-Check number of files in Blob-directory
-Stop running Prater/Goerli Beacon

-Restart Beacon
