REFACTOR: Remove `.erb` file from javascript tests

We can't use erb in Ember CLI (since it does not have Ruby) so this has
been ported to use our `javascript:update_constants` rake test instead.

Note we don't have to run this every time a notification type as it's
only used by fixtures to fill in some specific types we test against.
