code: public DelegateEbeanServer withPersisting(boolean persisting) {
      persistBulkUpdates = persisting;
      persistDeletes = persisting;
      persistInserts = persisting;
      persistUpdates = persisting;
      persistSaves = persisting;
      return this;
    }
docs: Set to true for all the persisting calls skip/avoid calling the underlying delegate.
  <p>
  So when set to true then all the calls to save(), delete() etc do not get passed on the
  the underlying delegate.
