Find references doesn't work with default exports when importing with a different name

[use-strict]

TypeScript Version: 2.0.3

Code

// A.ts
export default class A {
}

// B.ts
import AA from './A'; // <----Imported as AA instead of A

Expected behavior:
Find all references on class A finds the usage in B.ts
Actual behavior:
No references are found

This limitation is going to being especially noticeable when using the new VSCode references code lens: microsoft/vscode#18205

@waderyan FYI, we probably need to prioritize a fix for this, so let's make sure we talk about this at our next meeting

I have an additional suggestion. If it happens to be a locally anonymous default class or function it would be great to have find all references be a valid action to perform on the default keyword itself. Right now I sometimes add names to default exports when I otherwise wouldn't just in order to make find references work. This doesn't feel right because the identity should come from the module, not the name.
