chore(protractor): update protractor to ~4.0.13

[cnishina]

package.json

• Removed Protractor. npm test does not appear to be using Protractor.

packages/angular-cli/blueprints/ng2/files/package.json

• Update to protractor 4.0.13. see changelog
• Remove webdriver-manager as a dependency. Protractor includes
  webdriver-manager as a dependency.
• Since packages/angular-cli/blueprints/ng2/files/protractor.conf.js uses
  directConnect with chrome, the pree2e step does not need to download
  the selenium standalone server or gecko driver.

updated Travis

• test linux to use chrome per http://blog.500tech.com/setting-up-travis-ci-to-run-tests-on-latest-google-chrome-version/

😦 chromium does not play well with the latest chromedriver. changing the title to WIP

Just tag me when you're ready for a review, I'll change the labels and do it :)

Travis was green (we're low on resources so I killed it before it finished the optional tests). Let me know if this is still Work In Progress or if it's ready for a review.

Ran locally

./bin/ng new tmp
cd tmp
ng serve &
ng e2e

console output:

• only downloads chromedriver
• the initial test passes

❯ ng e2e                                                                                           ⏎
