fix(setup): dep and scoped imports

[NathanWalker]

@vinckobb This works. A couple things I noticed from your comments on the repo.

• Looks like you are on Windows, is that correct? Could be something particular there.
• This changes to core modules 6.3 and a specific runtime however should work just fine with 6.4, I just have those specific runtimes installed so feel free to change runtime to 6.4 and core modules back to what you had after merging.
• The most important could possibly be that I updated the imports to use @nativescript/angular which may help the Ivy compilation since that's the direct package (instead of the compat reference).
• Also the "ngcc" reference in scripts may also be important.

For instance, when clearing you project completely and building fresh with:

tns run ios --emulator --env.aot --no-hmr

You should absolutely see the ngcc output during the build like this:

Warning: Entry point '@nativescript/angular' contains deep imports into '/Users/nathan/Documents/github/NathanWalker/tmp/nativescript-angular-demo/node_modules/tns-core-modules/ui/core/view/view', '/Users/nathan/Documents/github/NathanWalker/tmp/nativescript-angular-demo/node_modules/tns-core-modules/ui/layouts/layout-base', '/Users/nathan/Documents/github/NathanWalker/tmp/nativescript-angular-demo/node_modules/tns-core-modules/utils/types', '/Users/nathan/Documents/github/NathanWalker/tmp/nativescript-angular-demo/node_modules/tns-core-modules/file-system/file-system'. This is probably not a problem, but may cause the compilation of entry points to be out of order.

Note that last line where it mentions @nativescript/angular. If you don't see that then ngcc for ivy prep is not running right on your end.

Hope this helps.
