Deleted data is still accessible using history

What happened

Deleted data is accessible using Key Value History or SQL select * from (history of table_name).

What you expected to happen

Deleted data should be unreadable and only present as hash, to validate the immutability of the database.

How to reproduce it (as minimally and precisely as possible)

In immuclient:

set keyname bigvalue
delete keyname
history keyname

Environment

# run "immu* version" and copy/paste the output here
