Title: Move if and unless tests to only live in ember-htmlbars

For you @rwjblue. This demonstrates a non-duplicated-tests plan for migration handlebars helpers to htmlbars. The htmlbars test runs over handlebars helpers by default, and with the feature flag runs htmlbars tests. Tests not yet ready to be run with htmlbars can be blocked by an inverse feature flag.
