Hygiene: Dont save phpunit handlebars compilations

The original method used to compile templates in this test
results in leaving behind new compiled files in handlebars/compiled
that were never before created(due to being used as a partial instead
of directly).

This patch adjusts to create and evaluate the template on the spot rather
than writing it out.
