import * as & export * as does not work.

Bug report
Using import * as and or export * as results in an empty output d.ts file.

Input code
one.ts

export class One {}

two.ts

export class Two {}

combine.ts

import * as One from "./one";
import * as Two from "./two";

export { One, Two };

Expected output

// Generated by dts-bundle-generator v7.2.0

declare module One {
    export class One {
    }
}

declare module Two {
    export class Two {
    }
}

export {};

Actual output

// Generated by dts-bundle-generator v7.2.0



export {};

Additional context
Dts-bundle-generator version: 7.2.0
