USAGE: ruby-rewrite -l controller_actions_keyword_args.rb -m <FILE>

This rewriter moves your Rails controller tests from `get action, params, session, flash` to
`get action, params: params, session: session, flash: flash`.

Which is needed if you see the following message in your Rails 5.0 tests :

DEPRECATION WARNING: Using positional arguments in functional tests has been deprecated,
in favor of keyword arguments, and will be removed in Rails 5.1.
