Bug of not applying regional effects such as +20 armor to units recruited in province w/forge of hashut resolved by passing region_key to spawn_minor_cult_by_key function instead of the region object itself.

This should fix it for all such effects, but i only tested forge of hashut.

This line:
spawn_minor_cult_by_key(region, cult_key)

Changed to:
spawn_minor_cult_by_key(region:name(), cult_key)

spawn_minor_cult_by_key function expects region_key, not region object:

function spawn_minor_cult_by_key(region_key, cult_key)
for i = 1, #MINOR_CULT_LIST do
if MINOR_CULT_LIST.key == cult_key then
spawn_minor_cult(region_key, i);
break;
end
