normaliseType is not well-kinded

Suppose we have

Proxy :: forall k. k -> Type

type family F a
type instance F Int = Bool

and we're trying to normalise the target

Proxy (F Int) x

Clearly, for this target to be well kinded, we need x :: F Int. Currently, the output of normaliseType is Proxy Bool x, which is just plain wrong.

I need to implement logic like in flatten_args on my branch in normaliseType to fix this.
