Fix imports used in member props

[mischnic]

Previously, it didn't continue visiting the property part of member expressions, thus imports used in there were ignored (and then incorrectly excluded from the bundle).

In this case, the import only had the import foo1 but not foo2 registered. Then foo2 became undefined at runtime

import { foo1, foo2 } from "../test/b.js";

var _a = {};
_a[foo2] = "foo";
console.log(foo1, _a);

Closes #9275
