Rename file when renaming default export

Currently we can use the rename symbol command and that will rename the symbol and its usages (exports, imports, usages in other files, etc.). That's a great start, but I'd love to see this feature expanded to do the following:

• Many times a file name will coincide with the symbol being refactored. The refactor option should be available when renaming the file, so everything can be done at once.

• In addition to the refactor changing symbol references across all files, it'd be nice to have the ability to also update comments, strings, etc. that refer to that symbol.

Code Example:

Shape.js

class Shape {}
export default Shape;

Circle.js - We reference Shape as an import, extends, inside a comment, and inside a string. They should all be refactored.

import Shape from "./Shape";

// Shape subclass
class Circle extends Shape {
  constructor() {
    super();
    console.log('A circle is a Shape.');
  }
}

export default Circle;

WebStorm Examples

Start with the existing rename symbol command and trace how it updates exports, imports, and usages across files. Use the Shape.js and Circle.js example as the acceptance case: renaming the default export should also rename the matching file and update the shown import, comment, and string references.
