Find all references doesn't find all results and crashes tsserver if `type S = import().S` syntax is used

<!-- Please try to reproduce the issue with the latest published version. It may have already been fixed. For npm: `typescript@next` This is also the 'Nightly' version in the playground: http://www.typescriptlang.org/play/?ts=Nightly --> **TypeScript Version:** 3.9.0-dev.20200223, 3.8.2 <!-- Search terms you tried before logging this (so others can find this issue more easily) --> **Search Terms:** Find all references crash tsserver reexport **Code** [Reproduction repo](https://github.com/InExtremaRes/find-references-ts-bug/tree/bug1) file1.ts ```ts export class Foo {} export class Bar {} ``` file2.ts ```ts import * as f1 from './file1'; export class Container { readonly classes = f1; } declare const c: Container; c.classes.Foo; // Uncommenting this line make 'Find all references' work again // export { f1 }; ``` file3.ts ```ts import { Container } from './file2'; declare const c: Container; // 'Go to definition' works from here but 'Find all references' doesn't show this line c.classes.Foo; ``` **Expected behavior:** All three references to `Foo` are shown, in `file1.ts`, `file2.ts` and `file3.ts`. **Actual behavior:** Reference in `file3.ts` is not shown. **Workaround?:** Uncommenting `// export { f1 };` in `file2.ts` makes all references to be found, even if no other file imports `f1`. --- <details> <summary> EDITED (2020-02-23): I tested this section with TS 3.8.2 and doesn't crash tsserver anymore</summary> In the same repo, but [another branch](https://github.com/InExtremaRes/find-references-ts-bug/tree/bug2) it is shown that with a new file: file4.ts ```ts type S = import('./file3').S; ``` find all references on `Foo` crashes tsserver. Changing file4 to: ```ts import { S } from './file3'; ``` avoid the crash. The [tsserver.log](https://github.com/InExtremaRes/find-references-ts-bug/blob/bug2/tsserver.log) shows: ```plain {"seq":11,"type":"request","command":"references","arguments":{"file":"/tmp/find-references-ts-bug/file3.ts","line":5,"offset":12}} …
