RSpec::Rails::Matchers::RenderTemplate::RenderTemplateMatcher#check_redirect

Uses normalize_argument_to_redirection to find and format
the redirect location. normalize_argument_to_redirection is private
in ActionDispatch::Assertions::ResponseAssertions so we call it
here using #send. This will keep the error message format consistent
