[1.5.x] Fixed geos test to prevent random failure

            for i in range(len(mp)):

                # Creating a random point.

                pnt = mp[i]

                new = Point(random.randint(1, 100), random.randint(1, 100))

                new = Point(random.randint(21, 100), random.randint(21, 100))

                # Testing the assignment

                mp[i] = new

                s = str(new) # what was used for the assignment is still accessible
