TypeScript Call Hierarchy view fails to find callers for registerCommand in extension template

Found while testing microsoft/vscode#89386

Steps to Reproduce:

1. Use yo code to create a TypeScript extension
2. Open src\extension.ts and right-click on activate and look at "Calls from activate".

The view correctly shows that activate calls registerCommand.

3. Now right-click on registerCommand and look at "Show Incoming Calls".

Call Hierarchy view is empty and says "No callers of 'registerCommand'".

@rbuckton @RyanCavanaugh Can we please investigate this for TS 3.8 (either for the final 3.8 release or for a 3.8.x recovery build that VS code would be able to pick up)
