Fix TaggedTemplate evaluation bug

This line of code causes a type error since `TaggedTemplateLiteral`s do not have a property called "expressions".

This change does what is probably expected. However, to maintain the existing behaviour, the line should instead be:

```js
const exprs: Array<undefined | NodePath<t.Node>> = path.isTemplateLiteral()
    ? path.get('expressions')
    : []
```
