[#20446] mathutils: bugfix for matrix * matrix - patch by Paul Parchenko (parfoure) thanks

>From the tracker:
- typo was making the multiplication to transpose resulting matrix
eg
####
from Mathutils import *
from math import radians

cont = GameLogic.getCurrentController()
owner = cont.owner

owner.worldOrientation = RotationMatrix(radians(1), 3, 'z') * owner.worldOrientation
####
