Deprecation warning in Rails 5.2rc1 when using self_and_descendants

[timdown]

The warning in my particular case with a model called Folder is:

DEPRECATION WARNING: Dangerous query method (method whose arguments are used as raw SQL) called with non-attribute argument(s): "folder_hierarchies.generations asc". Non-attribute arguments will be disallowed in Rails 6.0. This method should not be called with user-provided values, such as request parameters or model attributes. Known-safe values can be passed by wrapping them in Arel.sql().

@timdown feel free to put together a PR--I'm not contributing code to closure_tree anymore, but I'm happy to accept PRs and push new releases. I'm looking for more maintainers, too.

@mceachen Thought you might say that :) I'll have a go at this in the next week or so but I doubt I'll be able to commit to being a maintainer. By the way, this gem has been great for us. I just dropped it into our project (which involves a hierarchical folder structure) with minimal effort and it's worked flawlessly for years, so thank you for all the work you've done on it.

Looks like #296 fixed it. I failed to try the latest code before raising this. Sorry.
