* Fix initialiser why: Possible crash (app profiling, tracer etc.) * Update column family options processing why: Same for kvt as for aristo * Move `AristoDbDualRocks` backend type to the test suite why: So it is not available for production * Fix typos in API jump table why: Used for tracing and app profiling only. Needed some update * Purged CoreDb legacy API why: Not needed anymore, was transitionary and disabled. * Rename `flush` argument to `eradicate` in a DB close context why: The word `eradicate` leaves no doubt what is meant * Rename `stoFlush()` -> `stoDelete()` * Rename `core_apps_newapi` -> `core_apps` (not so new anymore) |

The file accounts_cache.nim has been relocated
Background
The new LedgerRef module unifies different implementations of the legacy accounts_cache. It is intended to be used as new base method for all of the AccountsCache implementations. The legacy accounts_cache version has been removed.
This was needed to accomodate for different CoreDb API paradigms. While the overloaded legacy AccountsCache implementation is just a closure based wrapper around the accounts_cache module, the overloaded AccountsLedgerRef is a closure based wrapper around the accounts_ledger module with the new CoreDb API returning Result[] values and saparating the meaning of trie root hash and trie root reference.
This allows to use the legacy hexary database (with the new CoreDb API) as well as the Aristo database (only supported on new API.)
