ShapeTracker note fixes

[jshiwamV]

will probably close this pr if i think its not needed

EDIT: the change is valid, that's how View.permute() comutes the transpose of shape in the sample example mentioned in this blog

a = View.create(shape=(3, 2), strides=(2,1))
print(a)
# Transpose it
a = a.permute((1, 0))
print(a.shape) # (2, 3)
print(a.strides) # (1, 2)

a = a.reshape((3, 2))
print(a)
