chore(typings): remove ptor from gulp types (#3307)

- after investigation, variables in the namespace cannot be assigned a value
- types will require import of the classes and then setting the value from global

  ```
  import {Browser} from 'protractor';
  var browser: Browser = global['browser'];
  ```

- update typing tests to set the value of the type
