Regression: Incorrect line number tracking

[richarddd]

Regression introduced by: #660

Line numbers are incorrectly reported

Reproducable

a.js

import a from "./b.mjs";
a();

b.js

export default async function () {
  return "abc" + a;
}

Output

qjs --unhandled-rejection ./a.mjs
Possibly unhandled promise rejection: ReferenceError: a is not defined
    at default (./b.mjs:1:1)
    at <anonymous> (./a.mjs:2:1)

Expectation (version 0.6.0, or parent commit c8be383)

qjs --unhandled-rejection ./a.mjs
Possibly unhandled promise rejection: ReferenceError: a is not defined
    at default (b.mjs:2:18)
    at <anonymous> (a.mjs:2:1)
