Fix error in bank integrations category matching objects.

Issue

Rookie mistake: the arrow function inside the map would not return a list of entries from which the object can be rebuilt. So it failed!

Didn't think about this earlier, but Object.fromEntries() is only available in NodeJS 12+.

Can we achieve the same with either some lodash functionality or just .reduce()?
