[Bug]: Human review action should be recorded instead of auto-approval

[ioanarusiczki]

What happened?

Followup for #15174 (comment)

1. There's a version that goes to the manual review queue which is flagged for HR but automatically approved
   https://reviewers.addons.allizom.org/en-US/reviewers/review/2244534
2. Going in admin to review queue history displays in the entry that it's been "approved"

What did you expect to happen?

Confirm approval should be the action displayed.

Note: the exit_date is correct -> belongs to confirm approval action

Is there an existing issue for this?

(This is about reviewqueuehistory)

ReviewQueueHistory.review_decision_log is set to the first activity resulted from reviewer tools action, which is why it's recording the approval here. But we should only do that for human ones, not automated ones: that version would stay in the queue until a human reviewer confirms the approval or makes another action, and that's when we should record.

The solution should simply be to avoid doing anything in ReviewBase.update_queue_history() when self.human_review is False.
