        Return the first DjangoTemplates backend that's configured, or raise
        ImproperlyConfigured if none are configured.

        This is required for preserving historical APIs that rely on a
        globally available, implicitly configured engine such as:

        >>> from django.template import Context, Template
        >>> template = Template("Hello {{ name }}!")
        >>> context = Context({'name': "world"})
        >>> template.render(context)
        'Hello world!'
