Summary

Check for is_iterable($object) (available since PHP 7.1) to avoid an exception calling foreach on $object in the rare case that the object is a custom Phorge class (PHUIBoxView, PhutilSafeHTML) and not an array. cf https://we.phorge.it/rARC7570dd0da119627ff83bc6db3be06b51eb5b366b for a similar patch to handle PHP stdClass objects.

See downstream https://phabricator.wikimedia.org/T373316.

Test Plan

Unclear to reproduce the actual issue, likely something Feed related.
Open an existing JSON Paste at http://phorge.localhost/P1 and see that it still renders.
Open an existing JSON File at http://phorge.localhost/F1 and see that it still renders.

I see a red light in a unit test but it works on me after the patch src/parser/__tests__/ArcanistBundleTestCase.php - any comment on that? Anyway sgtm since it needs the foreach() stuff later.
