* Re-model persistent database access why: Storage slots healing just run on the wrong sub-trie (i.e. the wrong key mapping). So get/put and bulk functions now use the definitions in `snapdb_desc` (earlier there were some shortcuts for `get()`.) * Fixes: missing return code, typo, redundant imports etc. * Remove obsolete debugging directives from `worker_desc` module * Correct failing unit tests for storage slots trie inspection why: Some pathological cases for the extended tests do not produce any hexary trie data. This is rightly detected by the trie inspection and the result checks needed to adjusted.
