Handle Sum0 when rebuilding materialized view incrementally

create materialized view mat1 stored as orc TBLPROPERTIES ('transactional'='true') as
select t1.a, count(*) from t1

HiveAggregate(group=[{0}], agg#0=[$SUM0($1)])
  HiveUnion(all=[true])
    HiveAggregate(group=[{0}], agg#0=[count()])
      HiveProject($f0=[$0])
        HiveFilter(condition=[<(2, $5.writeid)])
          HiveTableScan(table=[[default, t1]], table:alias=[t1])
    HiveTableScan(table=[[default, mat1]], table:alias=[default.mat1])

java.lang.AssertionError: Found an aggregation that could not be recognized: $SUM0
