Ivy support (#674)

* chore(travis): Do not install custom yarn version (travis seems to be installing recent versions these days)

* feat(package): Switch to ng-packagr for packaging @uirouter/angular

* chore(package): update package.json scripts for ng-packagr style

* chore(package): update to @uirouter/publish-scripts@2.3.37

* feat(package): switch to peerDependencies for uirouter/core and /rx and require angular 8 peer dependencies

BREAKING CHANGE: uirouter core and rx packages are now `peerDependencies`.
You will need to explicitly install the correct versions of `@uirouter/core` and `@uirouter/rx` into your project.

before:

```
dependencies: {
  "@uirouter/angular": "4.0.0"
}
```

after (example -- versions will vary):
```
dependencies: {
  "@uirouter/angular": "5.0.0"
  "@uirouter/core": "6.0.1",
  "@uirouter/rx": "0.6.0",
}
```

Or, use this command to automatically install peerDependencies:

```
npx check-peer-dependencies --install
```

* chore(package): Build with Angular 8

* fix(angular8): Add static: true to ViewChild

* fix(lazyLoad): Remove dependency on angular/router in favor of using ivy

Ivy supports lazy loading of modules without depending on the ROUTES token from angular/router.

* feat(package): Drop support for Angular version 7 and lower

BREAKING CHANGE: UIRouter for Angular v6.0.0 now requires Angular 8 or higher

* test(angular-versions): Test against Angular 9

* test(typescript-versions): Test against Typescript 3.4 through 3.7

* test(angular-versions): Angular 9: npx ng update @angular/core @angular/cli --next

* test(angular-versions): Angular 8: remove package-lock.json
