PUT requests do not work

Hi,

I have a route which accepts `PUT` only which I'd like to call in my Cypress test but it doesn't seem to work when I use `cy.visit()`:

````
cy.visit({ route: 'my-route', params: { comment: 1 } });
```

I get this error:

```
CypressError: `cy.visit()` was called with an invalid method: `PUT`. Method can only be `GET` or `POST`.
```
