From the discussion of above PR, ti.start_date is normally set when ti transitions to the RUNNING state.
But the current ti.set_state method has set start_date even though the state is prior to RUNNING.

This creates an unstable situation where start_date is present in SCHEDULED and QUEUED ti generated by backfilling, but not in ti that is not.

This is an unnatural behavior for ti's state transitions, so we try to fix it.

We can also add test cases like below, but currently they are not passed.
If we get concensus about state matrix in #38632 , I can try to resolve it.
