* 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.

title: Identificare lo stesso elemento con diversi selettori jQuery

# --description--
Ora conosci tre modi per identificare gli elementi: per tipo: `$("button")`, per classe: `$(".btn")`, e per id `$("#target1")`.
Anche se è possibile aggiungere più classi in una singola chiamata di `.addClass()`, aggiungiamole allo stesso elemento in *tre modi diversi*.
Usando `.addClass()`, aggiungi una sola classe alla volta allo stesso elemento, in tre modi diversi:
Aggiungi la classe `animated` a tutti gli elementi di tipo `button`.
Aggiungi la classe `shake` a tutti i pulsanti di classe `.btn`.
Aggiungi la classe `btn-primary` al pulsante con id `#target1`.
**Nota:** Dovresti identificare un elemento e aggiungere una sola classe alla volta. Complessivamente, i tuoi tre selettori individuali finiranno per aggiungere le tre classi `shake`, `animated`e `btn-primary` a `#target1`.
# --hints--
Il tuo codice dovrebbe utilizzare il selettore `$("button")`.
```js
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?button\s*?(?:'|")/gi));
```
Il tuo codice dovrebbe utilizzare il selettore `$(".btn")`.
```js
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?\.btn\s*?(?:'|")/gi));
```
Il tuo codice dovrebbe utilizzare il selettore `$("#target1")`.
```js
assert(code.match(/\$\s*?\(\s*?(?:'|")\s*?#target1\s*?(?:'|")/gi));
```
Dovresti aggiungere una sola classe con ognuno dei tre selettori.
```js
assert(
code.match(/addClass/g) &&
code.match(/addClass\s*?\(\s*?('|")\s*?[\w-]+\s*?\1\s*?\)/g).length > 2
);
```
Il tuo elemento `#target1` dovrebbe avere le classi `animated` `shake` e `btn-primary`.
```js
assert(
$('#target1').hasClass('animated') &&
$('#target1').hasClass('shake') &&
$('#target1').hasClass('btn-primary')
);
```
Dovresti usare solo jQuery per aggiungere queste classi all'elemento.
```js
assert(!code.match(/class.*animated/g));
```
