[JS] Codecompletion: Modules

### Description

If you use JS-modules, the codecompletion does not work as expected:
m2.js:
```
'use strict';
export function test(){
alert("test called");
}
```
m1.js:
```
'use strict';
import * as example from './m2.js';
```

if you type "example." the function "test()" is not found.

Reproduce the issue using the m1.js and m2.js examples, then inspect the JavaScript code-completion behavior for the imported module. The work is complete when typing "example." in m1.js offers the exported test() function from m2.js.
