Auto imports does not work for extensions

[mjbvz]

Testing: microsoft/vscode#37177

1. create a hello world JS extension
2. open extension.js
3. start to type RelativePattern
4. complete it

=> no import is added

Imho if there is no import action after accepting a proposal, we should also not show it in the IntelliSense window.

Copied from original issue: microsoft/vscode#37282

@mjbvz can you elaborate on the issue. i am not sure i understand

Repo

1. Run yo code to create a vs code extension
2. Select and generate a new js extension
3. Open the generated extension in VS Code insiders and then open the extension.js file
4. At the top of the file, type out Relative so that RelativePattern is shown as a completion item

Expected
Selecting this item should add an import for RelativePattern from 'vscode'

Bug
Selecting this item only does the completion. It does not add the import

With TS 2.6.1 I see this for the error being printed when we request the details:

This also isn't working in an empty TS project with two files a.ts and b.ts where b.ts contains export const bbb = 0;.
It looks like the list of entryNames we're getting from vscode doesn't have source properties set.

Info 105  [12:59:34.526] request:
    {"seq":17,"type":"request","command":"completionEntryDetails","arguments":{"file":"/home/andy/sample/ts/src/a.ts","line":1,"offset":3,"entryNames":["bbb"]}}

Should be: "entryNames": [{ "name": "bbb", "source": "/home/andy/sample/ts/src/b.ts" }]

EDIT: Never mind, just needed to install the new update. 🎊 Will investigate more.
