Subject: [PATCH] (stable) Fix a possible `count(null)` in PHUIInfoView

Summary:
See <https://discourse.phabricator-community.org/t/php7-2-exception-count-parameter-must-be-an-array-or-an-object-that-implements-countable/1031>.

PHP7.2 raises a warning about `count(scalar)` (GREAT!) and we have one here if the caller doesn't `setErrors(...)`.

Test Plan: Sanity-checked usage of `$this->errors`.
