Can't use type previously imported type from TS in newly converted TS file

[mtaran-google]

Repro:

1. Have file a.js, b.js. b imports a
2. Convert a into TS. The import in b will be changed to something like const aModule = goog.require('...'); const {a} = aModule;
3. Convert b into TS.

Expected: The import of a will be changed to import {a} from '...';

Actual: The import of a will be changed to something like import * as aModule from '...'; const {a} = aModule;. When you try using a in type position, TS compiler complains that it can't find the name.
