Bug: Class rename not updated in new expression

When a class name is renamed, the constructor call is not updated.

**Input**

```js
class c {}
const f = new c();
```

**Output**

```js
class wzpnig {}
const jnciqk = new c; // wrong
```

**Expected**

```js
class wzpnig {}
const jnciqk = new wzpnig();
```

The class declaration is renamed, but `new c(...)` still uses the old name
