template

In django templating you can use `{% extends parent_name %}` to indicate
that the template is derived from another. We use this feature along with
django-templated-email to have different base email templates for white-
label purposes.
The issue appears to be that `{% extends parent_name %}` does not get re-
evaluated when the variable changes, eg. from `email/app1.email` to
`email/app2.email`.
* The Engine uses `django.template.loaders.cached.Loader`
* The first time the template is loaded, the parent template is loaded
based on `parent_name` is loaded
* Subsequent emails load the template, but do not re-evaluate the
`extends`
If this is as-designed, how would one go about clearing out that cache. I
am using code like this (when setting up my test case) but it doesn't
appear to clear the cache, even though my `print()` debugging shows its
the same object (`<django.template.loaders.cached.Loader object at
0x113e99828>`_
{{{
for template in engines.all():
for loader in template.engine.template_loaders:
loader.reset()
}}}
