Bug: Re-ordered nested non-end BindingRestElement doesn't get transpiled

### Input Code

https://coffeescript.org/#try:(%7Ba%2C%20b...%2C%20c%3A%20%5Bd%2C%20...e%2C%20f%5D%7D)%20-%3E%0A%20%20x%0A

```coffee
({a, b..., c: [d, ...e, f]}) ->
```

### Expected Behavior
```javascript
var splice = [].splice;
function({a, c: [d, ...e], ...b}) {
var f;
[f] = splice.call(e, -1)
}
```

### Current Behavior
```javascript
(function({
a,
c: [d, ...e, f],
...b
}) {});
```

### Possible Solution

### Context

### Environment

* CoffeeScript version: 2.7.0
* Node.js version:

Reproduce the CoffeeScript example from the linked try page and compare the current output with the expected JavaScript shown here. Trace the compiler handling of the nested reordered BindingRestElement, then verify that the generated output removes the trailing element from the rest binding while preserving the expected destructuring behavior.
