Carl Schwan f3778bc9c7 fix(propagator): Improve lock behavior of propagator ...

Fix possible dead locks when running the propagator caused by two
requests updating the same amount rows in transactions.

- Lock rows always in the same deterministic order by sorting the
  path_hash first

- On all database outside of sqlite, also do first a SELECT FOR UPDATE
  to lock all the rows used in batch UPDATE calls, afterward to decrease
  the risk of two requests trying to lock the same rows
