[Bug] statementMerger uses 1st export default statement as default

[ops1ops]

Bug

Hey, recently ive noticed that after build plugin sets 1st default export in .d.ts to default even when i export as default not this statement. For example i have Header.tsx

import useHeaderLogic from './useHeaderLogic '; // useHeaderLogic has default export
...
const Header = () => {
  ...
  useHeaderLogic();
  ...
};

export default Header;

and after build Header-[hash].d.ts looks like this:

declare const useHeaderLogic
...
declare const Header
...
export { useHeaderLogic as default };

but expected Header to be default

and for example if i dont use default export in useHeaderLogic, Header becomes default in .d.ts, i think plugin just takes 1st default export (including imported modules)

Plugin version: 1.3.14
Typescript version: 4.0.2

upd:
probably this line of code creates export statements, i dont see any settings or something what depends on me, so i consider this is a bug
