Return element to make it chainable downstream

cy.type(text) returns the element so that other operations can happen.

Example of a simple form on a complex page with no easy selectors on the button:

```
cy.get('input[name="myinput"]')
      .clear()
      .fill(newText)
      .siblings('button').click()
```
