Fix character lists with character groups
Fix character lists with character groups

After the upgrade to Ruby 2.5, which removed top-level constant lookup,
we now have an error where we try to specify explicitly the path to the
Template class (to prevent a conflict with `ActionView::Template`). Fix
this by looking for the model as a top-level constant.
