ng g c doesn't add the component to NgModule if custom extension is used

[sis0k0]

If you have a shared project with a custom web extension, the generation of new components won't update the modules. Example:

Structure

src/
	app/
		app.module.web.ts
		...

Command

ng generate component random

Expected
The generated component should be declared inside app.module.web.ts.

Actual
The command fails, because it cannot find a module to declare the component inside.
