[Bug]: Add-on flagged for ratings threshold keeps getting reflagged for review even after clearing needs-human-review for its older ratings

[abhn]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

For an add-on that's flagged for ratings threshold

• the reviewer clears the needs human review flag as the flagging wasn't accurate
• the add-on review page is closed to let the add-on auto-approve
• the add-on got flagged again for review and ended up in manual review queue

What did you expect to happen?

• once an add-on review page is closed, the add-on is flagged again for review for Over ratings threshold for usage tier even though no new ratings were submitted for the add-on
• the ratings from the time of NHR-clearing should be excluded from re-flagging calculations, and the add-on should only be reflagged for this signal if it again gets enough ratings for it to exceed our thresholds
