A class which functions as a subject, but doesn't actually execute any assertions until
the promise has resolved. Once the promise succeeds, any method calls will be played back
on the result value of the promise.
@param {PromiseSubject} subject The subject wrapping the promise.
@param {Promise} promise The promise being tested.
