bug in object destructuring with computed properties

Bublé version 0.14.2

$ cat destructuring_computed.js 
var property = "Prop";
var { [property]: value } = { Prop: "foo" };
console.log(value);

Expected result:

$ cat destructuring_computed.js | node
foo

Transpiled code:

$ cat destructuring_computed.js | bin/buble
var property = "Prop";
var ref = { Prop: "foo" };
var value = ref.property;    // should be ref[property]
console.log(value);

Actual (incorrect) result:

$ cat destructuring_computed.js | bin/buble | node
undefined
