acts-as-taggable-on: undefined method `caching_tag_list_on?'

Since #403 was applied, I’m getting an error rendering a tag_list because the caching_xxx_on? method_on method has not been added. This is rails 4.0.2 working against the acts-as-taggable-on master. It seems that using base.connected? doesn’t work reliably on initialization and causes errors later if these methods have not been defined.

Stacktrace is not very interesting but here it is:

Showing /Users/aaron/sites/mixxter/app/views/admin/sites/_form.html.erb where line #5 raised:
