Fabien O'Carroll 15585971e2 🐛 Fixed async helpers nested in template helpers
closes #10643

The async resolver in express-hbs relies on storing the state of the
promises on the `this` value inside of a helper, which is always set to
the `context`. This patch updates our helpers which render templates, to
use `this` as the context when rendering their templates.
