/**
 * Returns the result of applying the onFailure function to the value inside
 * a failed promise. This is useful for handling rejected promises
 * inside function compositions.
 *
 * @func
 * @memberOf R
 * @since v0.26.0
 * @category Function
 * @sig (e -> b) -> (Promise e a) -> (Promise e b)
 * @sig (e -> (Promise f b)) -> (Promise e a) -> (Promise f b)
 * @param {Function} onFailure The function to apply. Can return a value or a promise of a value.
 * @param {Promise} p
 * @return {Promise} The result of calling `p.then(null, onFailure)`
 * @see R.andThen
 * @example
 *
 *      const failedFetch = id => Promise.reject('bad ID');
 *      const useDefault = () => ({ firstName: 'Bob', lastName: 'Loblaw' });

 *      //recoverFromFailure :: String -> Promise ({ firstName, lastName })
