revert: test(ngModelOptions): ensure input has focus in e2e tests

This reverts commit 8d38ec38921bf887189eb31b07855ca987beff47.
The protractor tests for ng-model-options were failing locally on Chrome
for me but this commit breaks the tests on Firefox.
chore(travis-build): don't re-package when testing docs

Since .travis is already running `grunt package` in the `before_script`
block there is no need to run it again when testing the docs.
chore(travis): disable captureTimeout

All of the recent failures were caused by too much load on SL, not
an actual problem.

I think a proper solution will be:

chore($http): remove deprecated responseInterceptors functionality

Code cleanup! response interceptors have been deprecated for some time, and it is confusing to have
two APIs, one of which is slightly "hidden" and hard to see, which perform the same task. The newer
API is a bit cleaner and more visible, so this is naturally preferred.

BREAKING CHANGE:

Previously, it was possible to register a response interceptor like so:

    // register the interceptor as a service
    $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
      return function(promise) {
        return promise.then(function(response) {
          // do something on success
          return response;
        }, function(response) {
          // do something on error
          if (canRecover(response)) {
            return responseOrNewPromise
          }
          return $q.reject(response);
        });
      }
    });

    $httpProvider.responseInterceptors.push('myHttpInterceptor');

Now, one must use the newer API introduced in v1.1.4 (4ae46814), like so:

    $provide.factory('myHttpInterceptor', function($q) {
      return {
        response: function(response) {
          // do something on success
          return response;
        },
        responseError: function(response) {
          // do something on error
          if (canRecover(response)) {
            return responseOrNewPromise
          }
          return $q.reject(response);
        }
      };
    });

    $httpProvider.interceptors.push('myHttpInterceptor');
