Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: 6.0.0
• Cross-platform modules: 5.2.0
• Android Runtime: 5.2.0
• iOS Runtime: 5.2.0
• Plugin(s):

"dependencies": {
    "@angular/animations": "~7.2.0",
    "@angular/common": "~7.2.0",
    "@angular/compiler": "~7.2.0",
    "@angular/core": "~7.2.0",
    "@angular/forms": "~7.2.0",
    "@angular/http": "~7.2.0",

    "nativescript-dev-webpack": "~0.20.0"
  },

Describe the bug
After using tns migrate for a project with Angular 7, @angular/animations package is not updated - its still 7.x.x version.

To Reproduce

$ tns create myApp --template tns-template-hello-world-ng@5.2
$ cd myApp
$ tns migrate
# now check the project's package.json - `@angular/animations` version is still 7.x.x

Expected behavior
After migrate, the @angular/animations package should be migrated. In case it is not installed in the project before calling tns migrate, the migrate command should not add it.

Additional context
WORKAROUND: npm i --save-dev @angular/animations@~8.0
