Remove redundant asInstanceOf for liftable

Previous encoding of Liftables which had universe passed in
as a parameter required a cast to solve path-dependant
madness problems:

  trait OldLiftable[T] { def apply(u: Universe, v: T): u.Tree }

In this case compiler wasn't smart enough to find out that

  liftFoo(universe, foo)

returns the same type of tree we were working with (universe.Tree)
and we had to cast to make it work:

  liftFoo(universe, foo).asInstanceOf[universe.Tree]

Now this cast is redundant as universe is not a parameter of
Liftable's apply.
