[#560] node: Fix Put in multi REP with intersecting sets of nodes

Once the node was processed it skipped, at the step of forming
result in case when all nodes skipped, because processed for
previous REP, service mark the whole request as incomplete.

Example of policies which are unblocked:
- REP 1 REP 1 CBF 1
- REP 4 IN X REP 4 IN Y
  CBF 4
  SELECT 2 FROM FX AS X SELECT 2 FROM FY AS Y
  FILTER Country EQ Russia OR Country EQ Sweden OR Country EQ Finland AS FY
  FILTER Price GE 0 AS FX
