vscode-ng-language-service: Not working in standalone HTML files in larger project

Hi,

i have found very strange behavior. I tried your extension in my project, but it is working only in inline templates, not in standalone html files. But in my project i`m using our company npm packages which are not in public npm repository. So i wanted to reduce project to smaller footprint which i can put on github to reproduce problem.

But when i reduced it it started working also in standalone html files. Well i have to try to find when it stops working, but currently i don`t have that case. But definitely there is some problem when it stops working in standalone html files.
