Keith 05e8c204e9 Add quickcheck-classes tests for Stack
The tests are implemented by using a newtype wrapper `TestStack`. This is to
avoid creating `Eq1` and `Show1` instances for `Stack` itself, which are needed
by quickcheck-classes to run with GHC less than 8.5. Tests are automatically
generated by `traversalLaws` and `foldableLaws` using the `Arbitrary` instance
for `TestStack`.
