Aristo balancer clean up (#2501)
* Remove `chunkedMpt` from `persistent()`/`stow()` function

why:
  Proof-mode code was removed with PR #2445 and needs to be re-designed.

* Remove unused `beStateRoot` argument from `deltaMerge()`

* Update/drastically simplify `txStow()`

why:
  Got rid of many boundary conditions

details:
  Many pre-conditions have changed. In particular, previous versions
  used the account state (hash) which was conveniently available and
  checked it against the backend in order to find out whether there
  was something to do, at all. Currently, only an empty set of all
  tables in the delta layer has the balancer update ignored.

  Notable changes are:
  * no check against account state (see above)
  * balancer filters have no hash signature (some legacy stuff left over
    from journals)
  * no (shap sync) proof data which made the generation of the a top layer
    more complex

* Cosmetics, cruft removal

* Update unit test file & function name

why:
  Was legacy module
