test(core): regression test for mjolnir requireFailure wiring

Construct a Deck and verify pinch, pan, and click each have the
expected blocking recognizer in their requireFail array. Catches the
`requestFailure` typo class of bug without depending on TypeScript
flagging it through mjolnir's union type.
