Generated declaration missing generic

2@rc

Given:

export type Bar<X, Y> = () => [X, Y];
export type Foo<Y> = Bar<any, Y>;
export const y = (x: Foo<string>) => 1

If I compile this with "declaration": true", the generated declaration file looks like:

export declare type Bar<X, Y> = () => [X, Y];
export declare type Foo<Y> = Bar<any, Y>;
export declare const y: (x: Bar<string>) => number;

Notice that the typings for y are incorrect: the parameter x should be of type Foo<string> which is an alias for Bar<any, string>, however it is incorrectly typed as Bar<string>. The first generic to Bar has gone missing.
