Using rollupTypes generates invalid declaration file

[NoelDeMartin]

Describe the bug

The declaration files are generated normally without using the rollupTypes option, but if I set it to true the generated files are not valid. In particular, they generate the following:

declare interface Constructor<T = Object> {
    new (...args: any[]): T;
}

declare const _default: ServiceConstructor<;

export declare class MyService extends _default {
}

declare class Service {
}

declare type ServiceConstructor<T extends Service = Service> = Constructor<T> & typeof Service;

export { }

Notice how the line declare const _default: ServiceConstructor<; is missing the closing > and the generic value.

I know these classes and types may seem a bit weird without much context, but that's the simplest thing I've been able to do whilst reproducing the issue.
