LibJS: Fix BindingPattern::contains_expression() is name is expression

Browse source 
If any of binding pattern entry's name is expession
`contains_expression()` should return true.

For example:
```js
function evalInComputedPropertyKey(
  {[eval("var x = 'inner'")]: ignored}
) {}
```

`contains_expression()` should return true for the binding param in
this function.
