No completions for computed string properties

[DanielRosenwasser]

const otherThing = "otherThing";

interface Foo {
    ["thing"]: number;
    [otherThing]: string;
}

declare var x: Foo;
x./**/

Expected: completions for thing and [otherThing].
Actual: completions for only [otherThing]

Note that

const otherThing = "otherThing"

interface Foo {
    ["thing"]: number;
    [otherThing]: string;
}

declare var x: Foo;
x["/**/"]

does effectively the "right" thing and is a good regression test.
