[Spa] Introduce NoSpaFrontEnd option for testing purposes (#15)

[Spa] Introduces NoSpaFrontEnd (hidden) option for testing purposes (#15)

In order for us to ensure the templates are up to date with the latest changes on the .NET runtime, we want to have some tests that are able to build them (and run the server part independently) if necessary.

For that matter, we are introducing the NoSpaFrontEnd option which is hidden from the users and that can be specified in tests to remove all integration with the SPA frontend.

We will continue droping the files on disk, but there will be no npm restore during build nor we will try to launch the SPA proxy when the app launches.

We will have some tests on the ASP.NET Core repo that install the templates package produced by the repo and build the templates to at least catch build breaks that changes on ASP.NET Core can cause.
