fix(js_formatter): correctly handle placement of comments inside named import clause

[ah-yu]

Summary

FIx formatting of following case. It's strange that the export declaration doesn't have such an issue.

// input
import {} from /* comment*/ 'foo'
import {} from // comment
'foo'
import {a} from /* comment */'foo'
import {a} from // comment
'foo'

// before
import {} from /* comment*/ "foo";
import {} from "foo"; // comment
import { a } from /* comment */ "foo";
import { a } from "foo";

// after
import {} from /* comment*/ "foo";
import {} from // comment
"foo";
import { a } from /* comment */ "foo";
import {
  a, // comment
} from "foo";
