#13573: Cached template loader can return incorrect template

The cached.Loader's `find_template` method constructs a cache key based
solely on the requested template name and does not include the
`template_dirs`. This results in `find_template` returning the incorrect
template where a template with the same `template_name` was previously
loaded and cached from a different set of `template_dirs`. That is to say,
the function is overly non-injective.
For example, the following snippets return the __same__ `Template`. when
they should return a different template for `templates/foo/file.html` and
`templates/bar/file.html` respectfully:
{{{
#!python
from django.template import loader
a = loader.find_template('file.html', ('templates/foo',))
b = loader.find_template('file.html', ('templates/bar',))
}}}
Patch attached.
