Review Comment:
@KnightChess I think this pr wants to guarantee write consistency no matter
whether the `when matched then` clause is present or not.
So maybe better to split this UT to two, one has configured
`preCombineField`, and another not. And both of UT contains two cases that have
`when matched then` or not.
