-----------------------------------------------------------------
Root cause of this problem is that there is a gap between user task is applied
to FSM and {{FSMCallerImpl.lastAppliedIndex}} is updated, so we ran
{{Node#readCommittedUserLog}} in test, but {{FSMCallerImpl.lastAppliedIndex}}
had not been updated.
Note that waiting for the latch in {{ItNodeTest#sendTestTaskAndWait()}} when
tasks are applying doesn't guarantee that {{FSMCallerImpl.lastAppliedIndex}}
will be updated immediately.
