Fix bonuses of Rampart's Treasury and Fountain of Fortune

Change IDs of two special buildings in Rampart to make them identical with one in config files / game assets.

Original code was introduced in 0ca9f64 with those two IDs likely was typo. As result Fountain of Fortune +2 luck bonus was given to Treasury and Treasury's weekly bonus didn't worked at all.
