Core db+friends fix sync bail outs (#2026) 
* Aristo: Update schedule runner for `hashify()`

why:
  Width-first schedule walker overlooked resolvable vertex and ended in
  a deadlock situation

* CoreDb+Aristo: Update error code for fringe condition

* Ledger: Remove redundant extra MPT hashing statements

why:
  These statement were used for troubleshooting

* CoreDb: Couch medicine for legacy DB backend

why:
  MPT will occasionally enter inconsistent states after deletion, some
  dirty fix is randomly added to mitgate that.

The file accounts_cache.nim has been relocated

Background

The new LedgerRef module unifies different implementations of the accounts_cache. It is intended to be used as new base method for all of the AccountsCache implementations. Only constructors differ, depending on the implementation.

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.)
