IMPALA-7315: fix test_update_with_clear_entries_flag race

We need to wait for the subscriber to process the second update in order
to guarantee that the first update for that subscriber has been applied.
Otherwise there is a race window where the second subscriber may see the
older version of the statestore topic.
