Rewrite all tns-core-modules short imports

[sis0k0]

Problem

There are short imports in the source code of nativescript-angular. They should be removed, because they may be deprecated in later versions of the framework.
A short definition of short import:

An import that is shortened from tns-core-modules/something to something.

Example of short import:

nativescript-angular/tests/app/tests/style-properties.ts

Line 6 in bdd9ece

import { device } from "platform";

The above code should be rewritten to:

import { device } from "tns-core-modules/platform"; 

Note 1

All valid short-imports are the files and directories that are on the root level of the tns-core-modules package - https://github.com/NativeScript/NativeScript/tree/master/tns-core-modules. Here's a (not exhaustive) list:

• application-settings
• application
• color
• connectivity
• ...

Note 2

The nativescript-angular plugin is written in TypeScript. A nice solution would be to parse the source files, then find and replace all AST nodes that contain short imports.
