I imagine it stalls due to excessive loading at low speed. I can't see why it wouldn't unstall pretty promptly as speed increases, particularly as the electrical load would have shifted back to the batteries. Would the emergency generator couple to the network again automatically? Dunno. So you might end up having manually select it again as per ECAM.
A RAT stall in the go-around is perhaps not as unlikely as you'd think given the aircraft may be in direct law at the time of initiation and a massive overpitch and subsequent speed loss quite plausible. Moral of the story is to select the gear up first unless close to the ground.
