Title: Add tests for sequencing HLists of Kleislis

The one for Kleislis of ValidationNels results in an implicit not found
error and is commented out.

@larsh (or anyone else) do you know of a way to convince the compiler to pick up the sequencer for a Kleisli of a ValidationNel? (See commented out test)
