* add forwards slashes to path redirects

* fix cypress path tests again

* plese cypress

* fix: test different challenge

Okay so I literally have no idea why this one particular challenge
fails in Cypress Firefox ONLY. Tom and I paired and spun a full build
instance and confirmed in Firefox the page loads and redirects as
expected. Changing to another bootstrap challenge passes Cypress firefox
locally. Absolutely boggled by this.

AAAAAAAAAAAAAAA

* fix: separate the test

Okay apparently the test does not work unless we separate it into
a different `it` statement.

# --description--
`dispatch` 方法用於將 action 分派給 Redux store 調用 `store.dispatch()` 將從 action creator 返回的值發送回 store。
回想一下,動作創建者返回一個具有 type 屬性的對象,該屬性指定已發生的動作。 然後該方法會將一個 action 對象發送到 Redux store。 基於上一個挑戰的示例,下面的行是等效的,兩者都會調度類 `LOGIN` 類型的 action
```js
store.dispatch(actionCreator());
store.dispatch({ type: 'LOGIN' });
```
# --instructions--
代碼編輯器中的 Redux store 具有初始化狀過的 state包含 `login` 屬性當前設置爲 `false`的對象, 還有一個名爲 `loginAction()` 的 action creator它返回類型爲 `LOGIN` 的 action 然後通過調用 `dispatch` 方法將 `LOGIN` 的 action dispatch 給 Redux store並傳入 `loginAction()` 創建的 action。
# --hints--
調用函數 `loginAction` 應該返回一個 `type` 屬性設置爲字符串 `LOGIN` 的對象。
```js
assert(loginAction().type === 'LOGIN');
```
store 應該用屬性 `login` 設置爲 `false` 的對象初始化。
```js
assert(store.getState().login === false);
```
`store.dispatch()` 方法應該被用於 dispatch 一個類型爲 `LOGIN` 的 action。
```js
(getUserInput) =>
assert(
(function () {
let noWhiteSpace = getUserInput('index').replace(/\s/g, '');
return (
noWhiteSpace.includes('store.dispatch(loginAction())') ||
noWhiteSpace.includes("store.dispatch({type: 'LOGIN'})") === true
);
})()
);
```
# --seed--
## --seed-contents--
```js
const store = Redux.createStore(
(state = {login: false}) => state
);
const loginAction = () => {
return {
type: 'LOGIN'
}
};
// Dispatch the action here:
```
# --solutions--
```js
const store = Redux.createStore(
(state = {login: false}) => state
);
const loginAction = () => {
return {
type: 'LOGIN'
}
};
store.dispatch(loginAction());
```
