Analytics property throws "Call to undefined method" error

[rbraun75]

Problem noticed

Adding the analaytics property

$properties[AMPArticle::ANALYTICS_KEY] = array(
      '<amp-pixel src="http://mydomain.com/my_tracking_pixel.gif">',
      '<amp-analytics config="https://mydomain.com/analytics.config.json"></amp-analytics>'
    );

from your quick start example and rendering the article throws an Error:

Error: Call to undefined method Facebook\InstantArticles\AMP\AMPArticle::getContext() in Facebook\InstantArticles\AMP\AMPArticle->buildAnalytics() (line 207 of [...]vendor/facebook/facebook-instant-articles-sdk-extensions-in-php/src/Facebook/InstantArticles/AMP/AMPArticle.php).

Facebook\InstantArticles\AMP\AMPArticle->buildAnalytics() (Line: 281)
Facebook\InstantArticles\AMP\AMPArticle->transformInstantArticle(Object) (Line: 189)
Facebook\InstantArticles\AMP\AMPArticle->toDOMElement(Object) (Line: 38)
Facebook\InstantArticles\Elements\Element->render('', 1) (Line: 145)
Facebook\InstantArticles\AMP\AMPArticle->render() (Line: 55)

There is no getContext() method in AMPArticle, so adding analytics the way described in your example does not work.

Expected result

Analytics text in rendered AMP Article markup.
