Returns the path to the template file.

The file locator is used to locate the template when the naming convention
is the symfony one (i.e. the name can be parsed).
Otherwise the template is located using the locator from the twig library.

@param string|TemplateReferenceInterface $template The template

@throws \Twig_Error_Loader if the template could not be found

@return string The path to the template file
Returns the path to the template file .
