fix(transform/styled-components): fix spans of quasis when some quasis removed (#12240)

In CSS minification:

Input:

```js
styled.div`color: /* ${c} */ blue`
//         ^^^^^^^^^^    ^^^^^^^^ spans of `quasis[0]` and `quasis[1]`
```

Minified:

```js
styled.div`color:blue`
```

The one remaining quasi needs to have span which covers both original quasis:

```js
styled.div`color: /* ${c} */ blue`
//         ^^^^^^^^^^^^^^^^^^^^^^
```
