fix(orders): don't restate a platform the merchant already names

Trip rows read "Order - Uber Trip (Uber)". The suffix exists so you can tell
where to go and look; when the merchant is literally "Uber Trip" it says
nothing. What identifies a trip is its two addresses, and those are in the
Order details panel. Existing rows updated in prod.
