Fix positional to hash params transform for Ember 1.11/1.12 (#155)

* Enable HBS transforms for Ember 1.13.0 and below again

* Fix HBS transforms for AST difference in Ember 1.11/1.12

* Extract Ember version checks into separate module

* Reenable most positional param to hash pair tests

* Remove unused `ember-compatibility-helpers` dependency
