* Code cosmetics * Re-org `aristo_merge`, internally split into sub-modules why: Became a burden for maintenance because it hosts two different functionalities under the same merge paradigm: account/data merge and snap proof merge where the latter produces a partial trie. * Fix CoreDb tracer * Ledger: fix potential account vs. storage tree sync problems * Remove bound on the size of removable whole storage trees * Activate `test_tracer_json` |

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.)
