refactor: name every interaction's validation module the same

Three interactions had three conventions: choice paired validation.js with
validate.spec.js, textEntry paired validation.js with validation.spec.js, and
ordering paired validate.js with validate.spec.js. Each interaction now has
validation.js beside its parse.js, with a spec named after the module it covers.
