Image as numpy array fails when height != width

[JaviFuentes94]

with Drawing() as draw:
         draw.stroke_color = Color('black')
            draw.stroke_width = 2
            draw.line((50, 50),  (40, 20)) 
            with Image(width=150, height=100, background=Color('lightblue')) as image:
                draw(image)
                 image_arr = np.array(image)
                assert (image.height, image.width) == image_arr.shape[:2] 

This small snippet fails as the width and height are different. If we set them to be the same there are no issues, and the image_arr looks like it should.

Wand orders shape data as (WIDTH, HEIGHT, CHANNELS). Try

assert (image.width, image.height) == image_arr.shape[:2]

Shape attribute order should be updated with correct values. Attaching to 0.6 release milestone.
