fix(expenses): no help line for "Företaget" in the Vem betalade select (#2330)

The button under it already says "Matcha mot transaktion", so the line
"Kort eller bankkonto. Matchas mot transaktionen när den syns." repeated
it. The other answers keep their line: it names the liability the company
takes on.
