Thats an unfortunate case, and lucky you had the original bulbs to hand!
On my last
Mk4 Ibiza it had aftermarket Xenon HID's fitted (being aftermarket, the car didnt feature headlight washers or auto-dipping beam) - the car flew through the MOT without any mention of the lights, or technicalities relating to them!
To an extent, it does come down to the individual who is testing your car.
You might have found the next garage just around the corner, would have not failed them either.
