normalizeValuesToDelete: Whether to normalize container values that are to be deleted, i.e. convert them from id-only to full data (MID-4863). TODO: 1. consider setting this parameter to true at some other places where it might be relevant 2. consider normalizing delete deltas earlier in the clockwork, probably at the very beginning of the operation
