Steps to Reproduce:

1. Have a file with a named export, that is typed like this:

export const getFoo: (input: number) => number = (input) => input;

2. Click "Convert named export to default" in the refactoring menu

3. The refactored code new lacks the typing

export default (input) => input;

I would expect the refactoring to maintain the functions typing. For example like this:

const getFoo: (input: number) => number = (input) => input;
export default getFoo;

After all, the intend of the refactoring is to change the type of the export, not the way the code is written. I mainly use this refactoring, to automatically change the imports in other files. So for me, just removing the export before const and add a new line with export default getFoo would be sufficient for this refactoring.
