The polling stations are always organized by the country that is holding the elections. When I voted in Finnish elections while living in Berlin, I had to go to the embassy of Finland for that, and it was the Finnish state that organized the voting there, not anything German.
Of course, at the same time: Why the heck would Moldova organize polling places in the Russia? Typically the voting from abroad happens in embassies and consulates, not elsewhere. If the Russia wanted to support Moldova having more consulates across the Russia, they could definitely have motivated Moldova to open them by being extra friendly to Moldova and Moldovans.
