Aristo: Update unit test suite (#2002)
* Aristo: Update unit test suite

* Aristo/Kvt: Fix iterators

why:
  Generic iterators were not properly updated after backend change

* Aristo: Add sub-trie deletion functionality

why:
  For storage tries linked to an account payload vertex ID, a the
  whole storage trie needs to be deleted with the account.

* Aristo: Reserve vertex ID numbers for static custom state roots

why:
  Static custom state roots may be controlled by an application,
  e.g. for a receipt or a transaction root. The `Aristo` functions
  are agnostic of what the static state roots are when different
  from the internal tree vertex ID 1.

details;
  The `merge()` function applied to a non-static state root (assumed
  to be a storage root) will check the payload of an accounts leaf
  and mark its Merkle keys to be re-checked.

* Aristo: Correct error code symbol

* Aristo: Update error code symbols

* Aristo: Code cosmetics/comments

* Aristo: Fix hashify schedule calculator

why:
  Had a tendency to stop early leaving an incomplete job
