Fix Pauli Kohberger's name stopping being drawn too early

This is because the y-position of the graphics.onscreen() check was a
little too high. Then their name (under Beta Testing) would suddenly
disappear too early. You'd have to look real close to spot it, but it
does happen. It's cuz the credits are all kinda hardcoded, which is
probably bad, but fixing that would have to come later...
